UI Improvements

• Add "Open with ILSpy" entry to the Windows Explorer context menu on exe and dll files (via Options/Misc)
• Added a "Debug Metadata Explorer" node for portable PDBs
• Empty metadata tables can now be hidden from the tree view
• "Select PDB" context menu: allows to change the PDB file resolved by ILSpy or pick one from a different location
• Various stability fixes

Enhancements
