Log:
- New $escmode (or EMBPERL_ESCMODE) to disable the possiblilty
to turn off escaping with a leading backslash. Adding 4 to
any escmode will cause Embperl to do no special processing
on the backslash. This is mainly to avoid problems with
cross site scripting issuse, where people are able to enter
aribtary HTML.
- Characters between 128 and 159 are all HTML escaped now to
avoid problems with buggy browser, which were reported to
treat the chars 139 and 141 as < and >.

Turn HTML and URL escaping on and off. The default is on ($escmode =
3).

+B<NOTE:> Normaly you can disable escaping by preceeding the item that
+normaly is escaped with a backslash. While this is a handy thing, it could
+be very dangerous in situations, where content that is inserted by some
+user is redisplayed, because they can enter arbitary HTML and preceed them
+with a backslash to avoid correct esaping when their input is redisplayed
+again. To avoid this problem, add 4 to the values below. This will cause
+Embperl to ignore the backslash when it does output escaping at all.
