UPDATE: Gameplay changes, bug fixes

Today's update includes the following:

• Changed bond-breaking priority so that rotating your solution will less frequently change its behavior. This will probably break any solutions you have that relied on ambiguous bonding or unbonding resolving in a particular way.

• Changed the trash and output instructions so that they happen after the movement and hydrogen manipulation instructions. This fixes some simulation oddities ("disappearing" hydrogen) and hopefully adds a little more optimization depth. This will also probably break some solutions.

• Reset histograms and leaderboards because of the above gameplay changes.

• Added tutorial text to the second puzzle better explaining that you can move and rotate precursors and emitters.

• Added hotkey support to the solution list (arrows, enter, Ctrl+N, Ctrl-C, F2 / Ctrl-R, delete).

• Added support for right-clicking to cancel playback and exit some screens.

• Removed the solution rotation button, as it sometimes breaks solutions. You can access the old behavior by pressing the F10 key. This is a deliberate attempt to hide the feature.

• Fixed a bug where dropping a new instruction in an invalid location would instead drop it in the top-left corner of the program grid.

• Fixed a bug where you could not clone single instructions when picking them up.

• Fixed a crash when clicking on instructions while dragging parts.

• Fixed a bug where emitter beams would flicker between outputs leaving and inputs spawning, which looked particularly bad in exported GIFs.

• Fixed a bug where some characters wouldn't show up correctly in solution names.
