`twitfetch.py` fetches the threads defined in `tweets.txt`, and
then the tmux.html has an example (will likely be made a macro
in the future)...

to make things generate properly..

not all are replaced as they could be confused for regular chars
(like x for times and - for non-breaking hyphen), so those will not
be changed..

css checking w/ the html checking as that works.. saves on invocation
of java..

files in it's own pass, and use find to identify them, since their
path name matching is broken..

add missing import macro...
X-UA-Compatible is no longer useful..
name -> id
various mismatched tags..

This causes issues w/ the atom blog as it puts html tags in the middle
of an html document where they shouldn't be..

more explicite...  It'd be nice to put everything in a div or something
that would scroll all the pre > code elements, but don't know how now..
