Fix title chars

[kovmir]

If # Title is the first line of a Markdown file, then swege sets <title>Title</title> as the page title.
If ### Title is used, then swege sets <title># Title</title> as the page title.

This pull request fixes that issue.

Thanks for finding and fixing the issue! I suggest replacing the for loop + variable approach with strrchr, which can do the same thing.

Consider this example title ### The importance of # character. The use of strrchr() would result in <title>character</title>.

Ah, fair enough. I suppose the previous solution is fine then.
