- made right swipe highlight when next swipe will generate

- added a swipe counter below right swipe
(could add a toggle for displaying it later)
- removed spammy console.logs from expressions index.js
- swipes no longer trigger under the following conditions:
- - when an input it focused
- - when character_popup or history popup are visible
- - when send_textarea has something typed into it
(I think this a bit too restrictive, may seek a smarter way to handle it)

ISSUE: Pyg repeating gens cause swipes animation to lag/freeze
not sure what is the cause, but should seek to remedy somehow.
