[PATCH v2 0/2] git-gui: reduce Tcl version requirement from 8.6 to 8.5

[Pratyush Yadav <me@yadavpratyush.com>]

Hi,

Some MacOS distributions ship with Tcl 8.5. This means we can't use
TclOO. So, use our homegrown class.tcl instead.

While here, fix a potential variable name collision by creating a
separate namespace for a chord's script evaluation.

Jonathan,

Can you please test the patches the same way you tested your original
series just to be sure we don't break anything? A review would also be
nice.

Changes in v2:
- Add a note _after_ checking if the user agreed to the deletion.
  Otherwise, if the user denies, two "zombie" notes are left lying
  around which will never be activated. This means that the chord won't
  complete and the index won't be unlocked, leading to git-gui becoming
  frozen.
