Add Travis CI?

[matthew-andrews]

Hey @csswizardry,

I wondered if you'd consider adding Travis CI to this repository so that any Pull Requests to this project could be automatically checked:

• for syntax errors;
• and $use-silent-classes continues to suppress all output.

If adding Travis is something that you'd rather not have, feel free to reject this (I do feel a bit guilty about suggesting to add 3 files to a project that only has 4). I was actually using this project as a convenient example of <blatantspam>testing an 'silent-all-classes' variable could be verified automatically</blatantspam> so it wouldn't be time wasted if the answer is no :-).

To benefit from this before merging this Pull Request you'll need to switch Travis CI on for this repository :-)

PS. My text editor took the liberty of trimming the whitespace on your README.md file: I can undo this if you'd prefer.

Good idea.
