* change regex matching potential hashtags

Matches any string starting with '#' and consisting of any number and combination of [A-Za-z0-9_] that is directly followed by whitespace or punctuation. Groups everything after '#' for access in functions using this regex.

This fixes #183 (incomplete links on hashtags containing special characters) by not matching these at all.

* also detect hashtags at the start of a paragraph

* restrict html tags after which to detect a hashtag

Hashtags should not be detected after just any html tag - for example not after an opening a or div. To still allow detection at the start of a line, allow specifically p and br to directly precede a hashtag.
