This is an umbrella issue for improvement of sources management in JPDA debugger.
Scheduling to future release. This needs some bigger redesign.
Integrated into 'main-golden', will be available in build *200902030229* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Log: #90398 - Stuff necessary for the redesign of Sources View.
Every session provider can define a "static" (not session-specific) content for a view.
Also an experimental support for tabbs is added.
