Syntax highlight in the TI-Basic viewer

[adriweb]

Basically just do like for the Lua editor: ed97832#diff-1ab30fd710566ccc19a3fd2a811c2057

Can we make it an editor too

[adriweb]

Yes that's #116 which is however a bit more complex but definitely on my todo list :P

[adriweb]

Available in the feature/basic-highlight branch: c7b71c8

Plz test and feedback :)

Added some more colors for labels/gotos and prgm*.
Also all lists are blue now.

Looks like it's good enough for master, since @mateoconlechuga keeps pushing for a merge :P

Maybe later we can add some color customization per syntax type...
