Remove some BBC Tags

First pass at removing some bbc tags from the core

Removes: acronym, flash, bdo, black, blue, ftp, glow, green, ltr, move, php, red, rtl, shadow, time, white

This removes them from parse_bbc, preparsecode, editor.js, css, etc ... lots of pink in the diff :smiley_cat:  Let me know if I missed any!
