Clean up some of the Apache config mod_rewrite rules

Thomas Berezansky suggested some improvements to the mod_rewrite
rules in eg_vhost.conf on the -devel mailing list; this is a stab
at correcting the most egregious problems.

Tested with Zotero and unAPI still works; tested with the staff
client and language-switching still works, as do the Conify and
Vandelay interfaces. Seems reasonably good.
