[orca-list] Added unbound keystroke indentation/justification toggle

[Jon <j orcauser googlemail com>]

Hi,

Just a little notification for those of you who are programmers.

I have just committed a small change to orca master, which adds a toggle 
for the speaking of indentation and justification. The keystroke is 
currently unbound.

I find it particularly useful when i am speeding through python 
code when proof reading, to be able to toggle the speaking of 
indentation.


Hope that it might be useful to someone.
