e comp - remove the disable/fast effects

for fast we probably should look at something like having a multiplier
on edj transitions and set it to 0 to make it instant. this would be
much better and able to apply to ALL effects... so let's remove this
way for now. as for no shaodws and other stuff - moving to wl cant
control CSD and even then it's a theme look ant feel - a "flat theme
withotu any shadows" would just not have them. probably not a checkbox
to have here.
