Format commit logs

Format of commits

See http://www.nmr-relax.com/manual/Format_commit_logs.html

1. The first line should be a quick summary under 100 characters. If sufficient and not too trivial, I use this for the relax release announcement.
2. A blank line.
3. A description and link to the support request.
4. Another blank line.
5. All the details in multiple paragraphs if needed.
6. The final blank line.

In base directory of the relax software, do

LONGER MESSAGE

Example 1

Fix for bug #20915, (https://gna.org/bugs/?20915) - Failure of Grace opening
in MS Windows

My name provided this patch, and was discovered during work on a
Windows 7 system: name _aaattt_ domain_dot_com

This is a small fix for a wrong call to "raise
RelaxMissingBinaryError(binary)", when issuing an external call to xmgrace.

The "path_sep" would be equal = [/], and the RE search would not find(True)
the full path specified for the xmgrace file.
This is now shifted to python: os.path.isfile
http://docs.python.org/2/library/os.path.html

Another fix, is that as a standard the command "xmgrace" is provided. This
will work fine through windows cmd, but the true name for program in windows
is "xmgrace.exe", and so an additional search for +".exe" is also performed.
