Implemented a new ini plugin

Because the simpleini plugin did not work too well for mounting the specification file and even failed to parse other ini files (e.g. samba), I wrote a new one. It uses a slightly patched version of the very small inih library (directly embedded). Although it works fine for now, it is still work in progress though. 

Improvements compared to simpleini:
* graceful handling of sections (keys are subkeys of their sections)
* support for comments (comments, are appended to the next non-comment key)
This section disables the eclipse formatter. Unfortunately the formatter doesn't honor manual formattings and just wraps lines at arbitrary positions. Especially for this constructor like KeySet creation the result would look really ugly
