Update change-notes and description

- Fix issue, where completion and resolving showed symbols that came from a
completely different project. The reason was that GlobalSearchScope does
not work as one would expect. This issue is fixed now and
resolving of external symbols from other files or libraries should work
correctly.
- Fix for a minor issue in resolving patterns from Rule. In a_ -> a, the
a_ should be green while the a is a global symbol
- External Mathematica libraries are now regarded as "being compiled" to
make navigation and resolving work correctly. You need to recreate your
libraries in your project settings!
- Fix local resolving of Condition expressions
- Fix for the FullForm viewer

The FullForm creator had a bug with blanks which is fixed
Small fix in hash of the package index
Fix for wrong completions that came from a different project

Fix subtreeChanged() to call super and minor refactorings

Finish 3.0pre10

Push version

Optimize recognition of changes in the highlighting

* The file-indexer for libraries and packages will now recognize usage messages
that are hidden inside an If[..] statement as this is sometimes used
* The unresolved symbol annotation is a bit slower now but should pick up
changes more consistently
* Contexts of packages are now available for completion
* Inside an empty (**) comment, it should now reliably work that sections and
author, etc. annotations can be completed with Ctrl+Space
* Non empty comments offer completion for function names
* The completion panel shows now the localization for local variables
* Hopefully fixed the "should not be null" assertion

Comment * inserter by default IDEA framework

This fixes the missing completion for file-global functions. Additionally,
this version includes a simple enter handler that inserts * automatically
in multi-line comments.
