in fixperms.bat

For new installs, change owner rather than giving 'F' permission to Users group
For existing installs, change owner and change 'F' permission to 'RX' for Users group
Local privilege escalation vulnerability
Introduced 2009-06-11, released in 0.7.5 2009-06-29
Reported by Juilo Cesar Fort of Blaze Information Security 2020-04-28

on localized versions of Windows.
----
Non-English versions of Windows do not have a Users group; instead they use a
localized group name. As a result, when installing I2P on a non-English Windows
box, the installer will show an error when trying to run the fixperms.bat
script.

Using the SID will work with any localized Windows. SID list @

(previous izpack was 3.7.2 from 2005-04-22)

izpack 4.3.0 from :

upack izpack:
java -jar IzPack-install-4.3.0.jar
or
java -jar IzPack-install-4.3.0.jar -console

get the standalone-compiler.jar from the installation lib/ directory:

This fixes the bug with the install windows centered in all the
workspaces, not the current workspace. And who knows what other
bugs in the last 4 years.

To fix Vista (and presumably Windows 7) permissiom problems,
add a run-privileged flag for those, and run the new fixperms.bat
which calls icacls to add the privileges to the install directory.

Add support for 6 more language packs found in the new release.
Change from ISO3 codes to native language names.

Disable creation of the i2p.tar.bz2 file in build.xml
(distributed as i2pheadless-0.7.x.tar.bz2), as izpack 4.3.0 now
supports headless installation with java -jar i2pinstall.exe -console.
Update INSTALL.txt and INSTALL-headless.txt accordingly.
