tweak and document abstract page

on file save: create parent directories if needed

unbreak command auto-completion (was broken since r0b92341adb6a - 52 commits ago)

chat: + added timestamps (can also be css styled and disabled) + allow exchanging stylesheet by just dragging a *.css file into the chat widget! + /saveStyleSheet command for keeping the applied stylesheet for future runs + /discardStyleSheet to reset to the saved/default stylesheet Note: I noticed command auto-completion is broken, don't know since when. annoying.

minor cleanups, mostly in own code

* fixing my hat preview bug nemo pointed out (thanks!) + cleanup of edit page loading, should speeed up application startup a bit.

improve and cash hilight regexp

highlight improvements * only highlight if surrounded by whitespaces (or trailing ': ') + case-insensitive

oops

Case-insensitive comparison of nicks
