Blockhead v0.6.0 alpha

Bigger release than usual. There have been many internal changes related to background tasks. I had one crash while testing the new catch buffer feature which I have not been able to reproduce since. As usual if you happen to find some way to consistently reproduce a crash or bug then let me know!

Update Notes:

• Feature: Individual volume control for tracks
• Feature: Added a widget to the bottom panel to show currently running background tasks
• Feature: Catch buffer
• Update: Moved settings buttons to bottom left of window
• Update: Moved device settings to settings panel
• Update: Combined volume controls with level meters
• Update: Added dB readouts to level meters
• Update: Made waveforms easier to see when a grayish/muted color is selected
• Update: Changed the way background tasks are managed
• Update: Stopped performing visual updates for level meters when they are not moving
• Bugfix: Harmonics editor sending incorrect values to the engine

Catch Buffer usage:

• Can be toggled open/closed by pressing F5, or the "Catch" button on the lower bar.
• Mouse wheel up/down to zoom in and out, middle mouse button + drag to pan left and right
• You can drag a custom region of the buffer by clicking and dragging left or right with the left mouse button.
• Whenever a new region is created, any regions that it intersect with are deleted.
• To create a new sample from a region of the buffer, click on it with the left mouse button and place the resulting block somewhere on the workspace. The new sample be named "Catch Data #n"
• You can trigger a preview of a catch buffer region by clicking the preview button at the bottom left of the region, or pressing the "toggle play" shortcut (currently spacebar) while hovering it with the mouse.
• You can trigger a preview from any part of the catch buffer by hovering over it with the mouse and pressing the "play from" shortcut (currently tab)
• The size of the buffer is currently hard-coded to ~45mb which is around 1 minute at 44100hz. There will be a user setting for this in the future.
