Chris Dent 895119af66 Send a warning when a yaml filename has an underscore (#157)
TestSuites are grouped by test runners by the name that is
generated for the tests within. To ease that grouping it is
useful to have filenames with a known set of characters.

Grouping is also used for py.test fixture handling.

This change raises a warning if a filename has an '_' in it,
effectively declaring that though it is possible to use '_',
it can impact grouping.

Fixes #144
