* All incoming form values now have stripslashes() ran on them automatically

* All incoming form values now have stripslashes() ran on them automatically
  (if PHP escaped them) if you include strings.php
* Removed sqStripSlahes (no need anymore)
* Completely fixed problem with some data needing escapes, some not, and some
  accidentally getting escaped twice (often in compose.php).

To use:
* Load strings.php at the beginning of your script
* All form variables are accessable as globals (as usual), but are without
  the escape backslashes (if PHP put any in).
