Batch modify notification emails could present a better description of the property change

[Ryan J Ollos]

On a batch modification to remove the keyword "abc", I noticed the body of the email was:

Batch modification to #613, #620, #565, #566, #575, #579, #584, #585, #586, #591, #598, #599, #611, #618, #610, #590 by rjollos:
keywords to abc

This could be more descriptive, and reflect what we see in the ticket comment: keywords abc removed.

Narrowing focus for milestone:1.2. Please move ticket to milestone:1.2 if you intend to fix it.
