Fix #156: clear weak mods on every key press

- new macro_mods bit field for mods applied by macros
- weak_mods now only used for ACT_{L,R}MODS (i.e. LSFT, RSFT, LCTL etc.)
- clear the _weak_ mods on every key *pressed* such that LSFT etc.
  can no more interfere with the next key

Adds a readme with a link to the blog post
