Lataa Hydrogen (Advanced drum machine for GNU/Linux) 1.2.4

This patch release fixes a number of bugs and inconsistencies found since version 1.2.3 and is generally recommended for all users.
Added
- Forward compatibility for .h2song, .h2pattern, .h2playlist, and drumkit changes introduced in version 2.0.
- MIDI and OSC commands
- CLEAR_SELECTED_INSTRUMENT - to remove all notes of the selected pattern associated with the currently selected instrument.
- CLEAR_PATTERN - to remove all notes of the selected pattern.
- INSTRUMENT_PITCH - to adjust the pitch of an instrument.
- OSC commands
- NOTE_ON and NOTE_OFF which are handled like incoming MIDI events without triggering their associated actions.
- CLEAR_INSTRUMENT - to remove all notes of the selected pattern associated with the provided instrument number.
- CLI option:
- -O/--osc-port to use a custom OSC port in both hydrogen and h2cli.
- -L/--log-file to provide a path to an alternative log file.
- -T/--log-timestamps to add timestamps to all log messages.
- --config to use a different user-level config file.
- --compression-level for h2cli to set the trade-off between max. quality (.mp3 and .ogg)/max. speed (.flac) (0.0) and max. compression (1.0) for exported audio files.
- Adding support for importing and exporting audio files of format .mp3, .opus, .au, .caf, .voc, .w64. Drumkits containing those formats can be loaded with older versions of Hydrogen too. libsndfile >= 1.1.0 is required on your system for MP3 support. (#2023)
- X-NSM-Exec entry added to org.hydrogenmusic.Hydrogen.desktop by @grammoboy2 (#2042).
- Delete key does now remove selected notes and notes under cursor in NotePropertiesRuler.
Changed
- Brazilian translation updated.
- Grid lines in the Song Editor are now rendered dotted to emphasize that this is the space the patterns in rather than objects in their own right.
- Virtual keyboard strokes are now mapped exactly as incoming MIDI NOTE_ON events (respecting both "Use output note as input note" and hihat pressure groups). But do not trigger associated actions (#1770).
- CLI option -d understand driver names regardless of capitalization.
- h2cli option -V is now able to handle whitespaces between flag and argument.
- h2cli long option for -k is renamed --drumkit -> kit in order to align the naming with the one used in hydrogen CLI options.
- Smaller keyboard cursor size with resolution set to off.
- Rename "J.Master" button into "Timebase".
