Trim saga: The big macros (#6269)

* adding trim: large macros and languageswitcher

* adding trim: KeyboardShortcuts.tid

* Hidden space to force some macros to be inline

This'll be our little secret. This single byte will actually allow
the uglifier to trim over thirty bytes while condensing.

I know I'm not supposed to optimize TW for some 3rd party plugin,
but I'm the one doing the whitespace trim work, so I'll give myself
this.

* More consistent nested quoting
