Bug 2835 - Inconsistent use of colon at the end of sentences

Bug 2835 - Inconsistent use of colon at the end of sentences

Labels which precede a text input or select typically have a colon
before them:

Name: [____]

This patch cleans up templates where labels in this context lack a
colon. Exceptions to this rule include radio buttons, checkboxes, and
labels inside tables.

To test, view the affected pages and confirm that labels look
consistent.

Patch adds more consistency.
Work for translators could be made easier using CSS instead
of whitespace after colon.
