Bug 436885 - c-source and h-source missing for latex

Original title does not cover problem anymore. Problem has evolved to that when clicking on the name for the source file (in LaTeX) a jump to the beginning of the document was made. This problem is fixed with this patch.

- operations on current index and node (next(), prev(), last(), first()) have been removed.
- access to internal nodes has been removed.
- old QList has been renamed to QInternalList for use inside qtools only.
- added type safe compare, new, and delete operations (compareValues(), newValue(), deleteValue()).
- add compareValues also to QDict for consistency.
- changed doxygen's implementation to comply with the new QList and QDict interface.
