This commit does the following:
 - A lot of shit I am really too tired to fucking write about
 - Absolute pathed telecomms scripting
 - Browser Datum traffic control
  - Absolutely lovely replacement for the fucking skin TCS window, using
    codemirror
 - CodeMirror integration for nanoUI
  - Sorta, I didn't work on this as much as I wanted to, because IT TOOK
