rncbc.org updates Qtractor (Linux) to v0.5.11

• Adding a track now inserts it after the current one, if any; one can also drag and move a track below the last one in the track list (main view left pane).
  
• Extended Edit/Select Mode/Automation: multi-selection mode, cut, copy, paste and delete of current track's automation curve nodes, now reached implementation ready status.
  
• Another old silent bug bites the dust: changing track names were dropping any track gain/volume and panning automation curves when saving the session.
  
• A primeval processing bug has been sorted out: aux-sends to audio output buses that just appear to be after the input bus where they're inserted were being left muted and silent (on a ticket follow-up by Holger Marzen, thanks).
  
• Fixed a sure crash bug exposed when processing of aux-send plugins when inserted too early on audio input buses chain (after a ticket report by Holger Marzen, thanks).
  
• Allow the build system to include an user specified CFLAGS (patch by Cristian Morales Vega, thanks).
  
• Shift/Ctrl keyboard modifiers now set to extend current clip selection while in main track view's Edit/Select Mode/Range, Rectangle modes.
  
• Main Edit/Select Mode/Automation icon retouched to look a bit more obvious and intuitive, hopefully
  
• Allow to change the velocities/values of the current selected events which have the exact same onset times and hide beyhond each other on the MIDI clip editor's pane below the main view piano-roll (ie. the one that represents MIDI event values as a bar chart).
  
• Fixed some problematic playback/export muting and annoying cleanup freezing, due on audio tracks with too many clips eg. more than hundred clip splits (hopefully fixes an issue reported by Louigi Verona, thanks).
  
• LV2 UI resize feature support/control added.
  
• Fixed dedicated MIDI control and MIDI metronome port connection restore conflict (thanks to jhammen catch & patch.
  
• New user preference option added: reverse middle-button role to Shift/Ctrl keyboard state, in special regard to edit-head/tail vs. play-head positioning while on the main track and MIDI clip editor (aka. piano-roll) views.
