Updating README.md making contribution/hacking guide/docs more available,

this is specially important for our GitHub impression which I suspect most 
coders will have their first meeting with I2P on. The documentation is far from
done but it should make value for any new developer by this time so I've decided 
to push them. It losly describes our build systems, and has a monotone cheat sheet 
which always has an "git equalent" so it's easier to handle for people used to git.

+
+## Build systems
+The build system of I2P today is a bit mixed. 
+In the old days, and at least for relasing we actually use
+the old `ant` tool. For the new Browser Bundle launcher, as 
+well as the Mac OSX launcher the `sbt` tool from the Scala 
+world was used cause it gives some increadibly effictive plugins
+and logic to build them while keeping a relation to the old build 
+system.
+
+We also have Gradle partly implemented, much work, but not all. Meeh 
+which is writing this readme is guessing we'll end up with a combination
+of Gradle and SBT in the end when we know what kind of structure we want.
+
+
+## Browsing around the source code
+
+If you're new at this, which we all was at one point, I'll have some tips.
+
+* Check out our [README.DIRECTORIES.md](README.DIRECTORIES.md) to learn ore 
+about where you'll find I2P's different parts in the codebase.
+
+* For me (Meeh), it worked well to run `find . -type f -name '*Runner.java'` 
+from the source tree root, and take a look at the files that get listed. A lot 
+of hints of how this is peaced together lies there.
+
+
+## The .. Monotone part

README.MONOTONECHEATSHEET.md

+# Monotone cheatsheet
+
+**Slogan:** *Saving you hours reading old manuals*
+
+For most of us developers using git, one of the columns will have an example of 
+how certain things are done in git, to easier know what to do in monotone.
