ludic.ui: <option disabled="{...}"> - a select steps past it, clamps off it and greys the arrow toward it

Browse source 
- The arrows, a press on the select and the pad step past a disabled option (ct_opt_step), wrapping
  as before.
- A value naming a disabled option is shown as the nearest enabled one (the lower of two as near) and
  set to it once the build is done: an event fired while the tree is built is cleared with the frame's,
  so the clamp is queued (ct_clamp_n / _i) and fired after nt_fired_clear.
- The < or > whose next option is disabled is drawn disabled (its part's :disabled), so a cycler shows
  where the options stop being on; it still steps past them.
- ct_build_select moves to controls_opts.ludic with the rest (controls_build.ludic 119 -> 104 lines).

Golden ui_select_disabled: options 3 and 4 disabled, a value of 4 clamps to 2, > is drawn disabled
there, > wraps to 0 and < from 0 steps back to 2. The 38 ui examples pass.
