Proposed update to commit template

[bandre-ucar]

After using the current commit template for a while, I'd like to propose a couple of minor tweaks.

• Move the fixes, user interface, and code review above the testing so it is more visible.
• include machine name and compiler as part of test suite info
• test status --> test answer changes: bit for bit, roundoff, climate changing,
• test summary:
  • summary of expected results (pass except for expected failures documented in the expected fails files.
  • details of unexpected results (new expected fails)

New template:

[ 50 character, one line summary ]

[ Description of the changes in this commit. It should be enough
  information for someone not following this development to understand. 
  Lines should be wrapped at about 72 characters. ]

Fixes: [NGT-ED Github issue #]

User interface changes?: [Yes (describe what changes), No]

Code review: [Names]

Test suite: [suite name, machine, compilers]
Test baseline:
Test namelist changes:
Test answer changes: [bit for bit, roundoff, climate changing]
Test summary:

[rgknox]

Looks fine to me.

I've updated the wiki.
