Osmorc Code

Added documentation for Apache Felix framework integrator.
Minor fixes in the documentation.

Autodetection of the facet now also requires the manifest file to contain a Bundle-SymbolicName
Invalid manifest files are handled a bit more gracefully.
Endhanced the build script to compile Osmorc and produce the plugin zip which also contains the helpset now.

Fixed typos

Added autodetection of Osmorc facets
OSMORC-3:
* exported required bundles of framework instance bundles are now added as dependencies to the module depending on the exporting bundle since IDEA libraries cannot have dependencies themselves.
* Libraries of a framework instance are removed when the framework instance itself is removed.
* Framework instance creation dialog is now centered on the settings dialog.
* Package references in a library manifest file are now searched in the project all scope since there is no module scope in this case.
* When a project uses a framework instance that is not yet available on the used IDEA installation, an undefined framework instance is created temporarily and for the next framework instance creation the name is preset to the name of this missing framework instance.

OSMORC-3:
* Framework instance libraries are now added as module dependencies when resolving bundle dependencies.

OSMORC-3:
