Add an icon (in OSX parlance, a 'bundle') to the installation folder to start
I2P.  

While there might be a better way to handle this (admittedly, I don't know OSX
that well), it is my belief that this way is less 'hackish' than the various
OSX 'installers' that I've seen floating around.

(either wrong architecture or i2psvc is just plain missing) and give
a more useful error message.

Add another commented example to wrapper.config for those instances in which bindipv6only causes problems

My rationale for this:
1) in case someone is installing I2P on top of an already existing installation
   this will cause I2P to be shutdown
2) no hangs during the installation if i2p is already installed as a service
3) in case the NT service settings are changed in wrapper.config by us, this
   will force the service settings to be updated.
4) versions of I2P < 0.8.7 did not remove the service when uninstalling. If someone
   removed I2P in the past and reinstalls I2P--opting to run as a service--the
   installation process will hang.

for use with a 32 bit JRE.

Rationale:
On an x64 system using a 32 bit jvm Without the 32 bit libwrapper, messages
like this will be shown in wrapper.log with the wrapper in MTN & I2P >= 0.8.7:

-----------------------
 Launching a JVM...
 WrapperManager: Initializing...
 WrapperManager: 
 WrapperManager: WARNING - Unable to load the Wrapper's native library 'libwrapper.so'.
 WrapperManager:           The file is located on the path at the following location but
 WrapperManager:           could not be loaded:
 WrapperManager:             $I2P/lib/libwrapper.so
 WrapperManager:           Please verify that the file is both readable and executable by the
 WrapperManager:           current user and that the file has not been corrupted in any way.
 WrapperManager:           One common cause of this problem is running a 32-bit version
 WrapperManager:           of the Wrapper with a 64-bit version of Java, or vica versa.
 WrapperManager:           This is a 32-bit JVM.
 WrapperManager:           Reported cause:
 WrapperManager:             $I2P/lib/libwrapper.so: $I2P/lib/libwrapper.so: 
                           wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)
 WrapperManager:           System signals will not be handled correctly.
-----------------------

With libwrapper.so removed, one sees the following:

 WrapperManager: WARNING - Unable to load the Wrapper's native library because none of the
 WrapperManager:           following files:
 WrapperManager:             libwrapper-linux-x86-32.so
 WrapperManager:             libwrapper.so
 WrapperManager:           could be located on the following java.library.path:
 WrapperManager:             $I2P
 WrapperManager:             $I2P/lib
 WrapperManager:           Please see the documentation for the wrapper.java.library.path
 WrapperManager:           configuration property.
 WrapperManager:           System signals will not be handled correctly.
-----------------------

The 32 bit lib names, when installed on an x64 system, will match the alternate
names that the wrapper looks for.

- removing from /build.xml
- moving recent changes from installer/resources/postinstall.bat to installer/install.xml
- dropping installer/resources/postinstall.bat

The aging v3.1.x of the java wrapper is being replaced in this
checkin with the latest (current) stable release, 3.5.9.

There is now only one copy of wrapper.jar, located in wrapper/all.
The build.xml scripts have been changed to reflect this new path.

All binaries--with the exception of solaris (I don't have 
SPARC hardware)--have been stripped.

FreeBSD x64 is being included in this release.

I have only included the x86 macosx wrapper due to not having a
system to test the x64 code on. On the plus side, the wrapper is 
universal (a FAT powerpc & Intel Mac) binary. No more prompting
to install Rosetta!

Don't prefer IPv4 but add the option commented out to wrapper.config. Make the option configurable in runplain.sh

In some distributions (such as Debian, for example) net.ipv6.bindv6only=1 is
set by default. In some configurations, networking in java applications will be
broken. Someone recently came into #i2p experiencing this very problem.

This change closes #464.

Braces were put around variable names so that router will run in kFreeBSD.
runplain.sh should now be shell agnostic (it runs in dash. it even runs in
*posh*, a ridiculously picky shell).
