Navigator edition+

Hi all! This release is all about making it easier to navigate around your project.

Major additions

• Pinned units show up above the piano roll.
  • Like in ptcollage, you can edit note durations but not pitch, which is useful for e.g. percussion.
  • Like the units in the side menu, you can Ctrl+Click to select them.
• There's a proper keyboard on the left side of the piano roll.
• The selection checkboxes in the side menu are replaced with checkboxes for pinning units.
  • You can continue to select units with Ctrl+Click over the unit names.
• Added mouse shortcuts to jump to another unit from the piano roll.
  • Hover over a faded background unit in the piano roll, then press R+click to jump to it!
  • You can also do this over a pinned unit. If you prefer, there's a setting to jump to a unit by clicking without R.

Minor additions

• When you hover over a unit in the side menu, it lights up in the piano roll and pinned units. Vice-versa as well.
• Ctrl+R toggles MIDI recording mode; previously recording was always on. (thanks @EwanGreen4 for contributing)
• You can use the scroll-wheel over number fields (tempo, time signature, pitch preview in the new voice window), to tweak their values
• Added a setting to change the default starting volume of a new unit (thanks @dimx88 for the suggestion)
• Ctrl+Shift+V pastes at the end of your selection, so you can use it as a stamp tool (thanks @dimx88 for the suggestion)
• Add configuration for editor & peak meter fonts (thanks @EwanGreen4 for contributing)

Changes from 0.6.0.2

• Fixed crash on shutdown (didn't break anything, just opened an error window on close)
• Added settings checkbox for following the seekhead exactly vs. jumping to it when it exits the window

Thanks to many people for iterating on these ideas, including @EwanGreen4, jaxcheese, Jade, dim, squiggy, and many others in the pxtone discord.

Huge thanks to @EwanGreen4 in particular for many suggestions, feedback, and contributions for this release. (Also, thanks @OPNA2608 for making it so easy to make a release, because I've had to rerelease 3 times now.)
