Rip and adapt koron/gelatin for our purposes
Very crude hook-up of keymap to ahocorasick keyseq
Still various stuff broken, but konami command kinda works
Tweak AcceptKey function

Now the functin properly handles unmatched sequences, and does the what
the original keybinding was supposed to do instead of doing... nothing
Update README
fix tests
check n.Value() before doing anything

should fix #139
one more crash to fix

Change rules for receiving key sequences

Various

* Alt key mod now work again
* Use TrimSpace

Start moving away from the old way of using the Keymap object
Remove global Keyseq, embed in Keymap
Various structural changes
