Radium

This release contains quite a few changes and improvements.

The biggest change this time is that the "locked instrument" concept
has been removed. Please let me know if this changes your workflow. It
is still possible to put back "locked instrument", but I would rather
not. Yust1n helped with this work.

A very big improvement this time is that window configuration is
finally remembered between sessions. Akimaze has implemented this
feature.

There's a new demo song called "Night comes" by Nay. This song even
exposed a bug in MacOS when handling Japanese characters which caused
Radium to crash. A workaround has been applied to this version of
Radium, if you have been bit by this problem before.

Faust has been updated from 2.54.9 to 2.70.3. Yust1n did the upgrade.

There's several other improvements as well, I'm not sure if I
mentioned the most important ones above, but I tried.


Changes 7.2.89 -> 7.3.84:

• MacOS: Don't crash when loading files with
  certain non-ascii characters (e.g. Japanese) in
  their filename. (Possibly only a problem in very
  recent versions of MacOS.)
• Demo songs: New song called "Night comes" by Nay.
• MacOS: Workaround for strange trackpad behavior
  causing two-finger-touching a seqblock not always
  working.
• Instrument: Remove the "locked instrument" concept.
  (Yustin / Kmatheussen)
• Instrument: Never automatically change instrument
  when playing song when the cursor is moved to a new
  editor track. (Yustin / Kmatheussen)
• Instrument: Replace the "locked" checkbox with
  a "select" button.
• GUI: Remember window positions and so forth between
  sessions. (Akimaze)
• Instruments Clarify what the "set new name" option
  does.
• Sequencer: Enable "Delete all selected" also when
  only one seqblock is selected.
• Sequencer: Remove the "Delete" popup menu entry
  since it was too similar to "Delete current".
  (It only differered for the behavior of assigned
  keybindings.)
• Automatically add extension to preset names if
  missing. (Akimaze)
• Faust: Use linear velocity->gain conversion for
  very low velocities so that gain can reach zero.
• Audio: Fix pops/scratches/clicks for quite silent
  sounds in the graph that were volume-boosted up
  later in the DSP graph. (Even the "Demo song" demo
  song suffered from this.)
• Build: Add option to use qwebengine instead of
  qtwebkit. (qwebengine has some shortcomings, but
  it can be convenient to use to avoid having to
  compile up qtwebkit.)
• Editor: Fixed coordinate calculation when dropping
  a file. (Akimaze)
• GUI: Option to use the alt key as a horizontal
  scroll modifier (in sequencer and mixer). (Akimaze)
• Faust: Update Faust 2.54.9 -> 2.70.3. (Yustin)
