Radium 6.9.96 released

[Kjetil Matheussen]

Lots of user interface cleanups in this release, plus some bug fixes.
Most important bug fix is for positioning modules in the modular mixer
when loading .mrec files.

Changes 6.9.94 -> 6.9.96:
* Editor: Make pitch expand/shrink also work on pitch
changes, not just on the main pitch of notes.
* Editor: Shorten the main popup menu a little bit.
* Editor: Fix editing the value of a pitch change.
I.e. left alt + return when cursor is placed on
a pitch change for a note.
* Playlist: Clean up popup menus a little bit.
* Playlist: Make it possible to configure the color
of the border of current entries.
* Playlist: Split the concept of current blocklist
position and the concept of current block, making
it convenient to change playlist while playing
song. I.e. current block is not always the same as
the current blocklist position anymore.
* Playlist: Clean up various things.
* Editor: Fix possible glitch in sound when cutting
the length of a note while playing.
* Playlist: Make "C" keybinding change color of
highlighted block or audiofile if mouse pointer is
currently pointing inside a block or an audiofile,
also in the blocks browser in the playlist for
instance.
* Playlist: Light up playlist entries when mouse is
above.
* Playlist: Select current seqblock under mouse when
mouse is above a playlist entry. This is practical
when assigning keybinding to e.g. change block
color.
* Playlist: Add popup menu option to set current
seqtrack.
* Sequencer: Fix some unnecessary jumpingaroundness
when moving seqtracks up and down.
* Sequencer: Fix changing timing mode
unintentionally when changing seqtrack order.
* Sequencer: Don't create undo when changing
seqtrack order but ends up with the same order as
before.
* Linux: Fix space and return key not working, for
some reason, on Ubuntu 20 and probably other
distributions.
* Sequencer: Don't show error message when trying to
swap last seqtrack with next seqtrack.
* Sequencer: Fix dragging seqtrack number up and
down when there are invisible seqtracks.
* Modular mixer: add the "Mixer" submenu to the
bottom of the effects popup menu.
* Mixer: Clean up the various "Insert plugin" menus.
* Editor: Clean up the top of the "(click me)" menu.
* Editor: Add the timing tracks popup menu submenu
to the bottom of the bars/beats popup menu.
* Modular mixer: Fix module positioning when loading
.mrec files.
* Ladspa: Include the name of the audio input and
output ports in the info box.
* Sampler: Fix integer overflow problem in code to
generate waveforms. This fixes (rare) situations
with no waveforms in the editor
* Mixer: Add "Create new bus" option to the top of
the list of buses you can send to when selecting
"Insert send".
* Mixer: Add "New bus" option to the main popup menu
in the modular mixer.
* Mixer: Tweak the "New sound object" / "New audio
instrument" menu.
* Sequencer: Change "Set name" to "Rename" in the
popup menus.
* Playlist: Fix block names not being updated when
editor blocks are renamed, and other situations.
* New song: Hide signature track, tempo automation
track, and swing track.
* Editor: Automatically (and continously) resize all
tracks to fill all available space for clean
projects.
* API:
* New: getSeqtrackUuid,
setCurrEditorBlockUnderMouseForSequencer,
getCurrEditorBlockUnderMouseForSequencer,
setCurrSampleUnderMouseForSequencer,
getCurrSampleUnderMouseForSequencer,
getCurrBlocklistPos, setCurrBlocklistPos.
* setUsingSequencerTiming gets optional argument
