Include file type in issues created from exceptions

[izuzak]

Example issue where this would have been helpful: atom/atom#5472 (see atom/atom#5472 (comment)).

Perhaps we could include the extension of the file and the grammar which was used (just like in the status bar)?

EDIT: might be helpful to include some other file-related info, such as the total size, the number of lines, longest line, permissions, encoding?

For atom/atom#5472, first-mate could definitely include the grammar path in the exception message to make it easier to know which grammar has a bad pattern.

For those looking to validate grammars, I made a quick and dirty checker at https://www.npmjs.com/package/seaworthy, which just loads the grammar and then tries to parse all of the patterns.
