[komar]

After upgrading trac to 1.2 I get error:

Traceback (most recent call last):

In 16172:

MilestoneTemplatePlugin 0.1.2: Fix incorrect import

Patch by komar.

Fixes #13027.

[Ryan J Ollos]

The fix was straightforward, so I took the liberty to push it. I hope that is okay.

The _ function has always been in the module trac.util.translation, so I imagine this only worked in Trac 1.0.x due to a transitive import.
