"application/x-dos-batch" is an unknown mimetype when Pygments is not installed

[Ryan J Ollos]

The WikiProcessor #!application/x-dos-batch is used on the TracRepositoryAdmin page. In an installation without Pygments, the following error will be seen:

I propose the following patch to fix the issue, followed by replacement of #!application/x-dos-batch with #!dos on the TracRepositoryAdmin page.

Pygment's ​BatchLexer defines the shortname bat for mimetype application/x-dos-batch in the latest release of Pygments, which is 1.6. dosbatch and winbatch have since been added to the mainline (changes made in ​414d4a1e and pulled in ​c3493668).

It seems like dos, batch and cmd are all reasonable guesses at a shortname for the mimetype, and they aren't used elsewhere in Trac WikiProcessors or Pygments, so I'll add bat batch cmd dos as short names for the mimetype application/x-dos-batch.

Committed to 1.0-stable in [12041:12042]. Merged to trunk in [12043:12044].

The TracRepositoryAdmin page was updated in revision 32. It had been edited to use the application/x-dos-batch in revision 9. I didn't find any other uses of #!application/x-dos-batch in the documentation.
