api {} blank (pull #99) AND a patch to handle XML Parameters

[brianhorakh]

I added / to the regex for @apiParameter parsing so we can document XML input output (using XPATH conventions) -- ex: Auth/UserId

This also includes my previous pull request #99 for @API {} which is a cheap hack for writing non-API method pages.

This looks good. Nice work.

Thanks. Will merge b98e99e in 0.7.0. but the type field must be set, it is not optional.

In 0.7.0 is a api-call function implemented, which need type too (it will be to complicated to check on every use if type is set). A separate include of .md files with / without navigation will be implementen in the next release too, so the empty type problem should be solved.
