Lataa Hydrogen (Advanced drum machine for GNU/Linux) 1.2.5

This patch release introduces Qt6 support, deprecates LASH support, and fixes a number of bugs and inconsistencies found since version 1.2.4.
Added
- CLI options --log-colors and --no-log-colors to enable and disable ANSI colors in log messages.
- CMake option -DWANT_QT6 to build Hydrogen using Qt6 instead of Qt5.
- CLI option --user-data for both hydrogen and h2cli to provide an alternative user-level data folder.
Changed
- The shortcut for starting/pausing transport can now be used while focusing spin boxes (like the BPM one) too (#2098).
- Combo boxes do not accept focus (and preventing shortcuts) anymore.
- LASH support has been deprecated and will be removed in version 2.0 of Hydrogen (#1649).
- Allow to select and copy version in About dialog (#2127).
- Number of parallel build jobs in build.sh is now set dynamically to number of virtual processors (#2128).
- Changelog was renamed CHANGELOG.md and converted from GNU-style changelog to markdown similar to https://keepachangelog.com/en/1.1.0/.
- Hydrogen no longer uses XSD files to validate XML files during loading or via h2cli --check but uses direct XML inspection instead.
- Minimal CMake version was bumped to 3.5.
- Option -qt5 was introduced to native Windows build script windows/Build-WinNative.ps1 to build against Qt5 instead of Qt6 (default).
- build.sh script compiles against Qt6 per default.
