movement optimisations

[myrrc]

• Don't use util functions as they're slow, retain them only for "big" items motions
• Debug mode for tester script, less output for single test, less sleep between commands
• New movements test
• curl instead of wget in tester
• sws bump to 2.14.0.3
• new FirstItemStart item mapped to ^
• no windows backslashes \ in rk.lua (lua guarantees to match forward slashes on every platform)
• Don't show .RPP files in Github diffs
• custom_actions folder removed in favour of movements.lua
  Resolves input latency #81

Thank you so much for this - Sadly this did not fix my problem, movement is still very slow.

I've poked around and found something that seems weird, but might be a clue:

hitting <SPC> to open the menu is INSTANT. hitting <ESC> to close the menu and re-focus the editor has THE SAME LAG as item movement.
That's strange, right?

I have just done what I should have done at the start, reinstalled reaper fresh, then installed reaper-keys. No lag. I'll compare my old config to this blank config, see what's gone wrong!
