Release 0.1.2

Will be out on this Friday:

- fixed: infinit loop occurred during removing modules from the core.
- changed: debug output information.
- fixed: minor bug in XdevLOpenGL under GNU/Linux.
- changed: static library goes now with the version number. By default all applications will use the version number for the core system. This means if you use the release 0.1.2. your xdevl application will look by default for the XdevLCore-0.1.2 shared object file. If you want to use different version use the attribute in the xml to do that.
