Reimplement Text Commands

[Jowan-Spooner]

• [x] speed

• [x] signal

• [x] pause

• [x] portrait (to change the characters portrait)

• [x] br

• [x] [word1,word2,word3] -> select a random word

  • [x] allow \,

• [ ] nw (would rename this tho, and make it a global setting)

• [ ] noskip # suggestion by @thebardsrc to not allow skipping on this event

Regrading [x,y,z], maybe this: https://github.com/coppolaemilio/dialogic/issues/971 should also be added here.

A 2nd vote for 'noskip'. May honestly backport that to 1.4.3. I badly need a nw, noskip option for cutscenes.
