Fix templates for CrashHandler

[chebee7i]

The default template for CrashHandler needed some updating to work with the .format() method of strings. Also, the parallel app no longer needed to define its own template.

Also, should profileapp.py define a CrashHandler and specify:

contact_name = release.authors['Fernando'][0]
contact_email = release.authors['Fernando'][1]
bug_tracker = 'http://github.com/ipython/ipython/issues'

for the contact information? Presently, if you receive an import error during the creation of a profile (eg creating a parallel profile without having zeromq), then none of this information is set.
