more tweaks to blogify

-	auto-recognition of Esotre (turn into Ēostre)
-	better recognition of (eg) 25c (turn into 25¢)
-	now recognizes 1/2 (turn into ½)
-	addition of ||- text -|| as a dialog block
-	Perl blogs now always use numeric footnotes
-	fixed bug in footnote() signature ($num should be optional)
-	add an extra bit of whitespace in front of blockquote when it's the first thing in the post
massive improvement in counting words in blog posts

fixed several bugs with the old method, including the problem where | (used in links) isn't a valid word separator
and sometimes word counts could come out negative
slight tweaks to shell startup file

better handling of colors in `less` via `$PAGER`
tab completion for `rmdir`
nicer output for `time`
some pretty sweet new features and fixes for `t`

-	`t -R`: run an individual test file via `perl` instead of `prove`
--		very useful if the TAP harness is eating your error message
-	`t -p`: run an individual test file through Devel::NYTProf to see where your bottlenecks are
-	`t -Nr` now uses `find -H` instead of `find`
--		this is more likely to DTRT
-	now exits after an error in your options
`pidgin_restore` now properly set chat window heights as well as positions

also added several more windows to the layout
overhauled to be more precise and fix some bugs

- wasn't counting the last week
- couldn't handle multiple birthdays in the period
`loc` (location, not lines of code) can now handle multiple files, and defaults to .
new switch for `perl-privatize`

`perl-privatize -e` privatizes, then edits
(similar to `perl-privatize -t`, except doesn't unprivatize afterwards)
`pusht` (^W in vi) now handles notes destined for $work's Trac system
new switch for `checktabs`

`checktabs -b`: bare (just print filenames)
a script to easily kill lingering Vagrant/VBox virts
make official the fact that myperl gives you `blessed`
