Comment entry field affected by commit message inspections

[leoluk]

The Gerrit plugin's code review comment entry box is affected by these commit message settings:

In particular, the "wrap when typing reaches the right margin" option interacts badly with review comments which are meant to be soft-wrapped by the Gerrit UI, rather than hard-wrapped by the author.

Perhaps it would be better to use a generic text area here vs. reusing the commit one?
