Fix mod stuck of MODS_KEY when leaving layer #62

- Add action_util.c and remove action_oneshot.c
- Add oneshot_mods for MODS_ONESHOT
- Add weak_mods for MODS_KEY and MACRO
- weak_mods is cleared when layer switching

- * Problem: Want to capitalize like 'The' but the result tends to be 'THe'.
- * Solution: Oneshot modifier have its effect on only one key coming next.
- *           Tap Shift, then type 't', 'h' and 'e'. Not need to hold Shift key.
- *
- *  Hold:       works as normal modifier.
- *  Tap:        one shot modifier.
- *  2 Tap:      cancel one shot modifier.
- *  5-Tap:      toggles enable/disable oneshot feature.
