Added abs, random_int, random_real, random_shuffle, random_select script functions.
Made == comparison of doubles use a small epsilon, so things like 3/2 == 1.5 are actually true.

New saturated multicolor and dark artifacts for magic-new-flip, magic-new-split, magic-new-promo, and magic-extended-art styles.

When saving files an older version number is used if that version of MSE would be able to open the set

Added I_DUP instruction

  * numbers are no longer auto converted to booleans, use to_boolean or != 0
  * booleans are no longer auto converted to numbers, use to_int
  * strings will soon no longer be auto converted to numbers, use to_int

Added version information ("since 0.3.7") to documentation

 TODO: don't allow the same set file to be opened twice, fork a window for it instead

  "Error message "String param1 has no member 'value'" when using param1.value in custom keywords."

Work around bug in wx path conversion from filenames in zip files for files with strange (unicode) names

show_pending_errors() was being called over and over again from the GUI
update system - somehow it managed to have a single thread in two places
at once. Also tried recursive mutex, resulted in infinite dialogs until
an out-of-memory crash.

Also, minor conversion fix.

The *_rule functions can now be considered deprecated
Documented this by removing mentions of the rule functions, except for a mention of backwards compatibility.

The plan is to deprecate rule form completely, so instead of replace_rule(match:..) write replace_text@(match: ...)

The idea is to prevent people from using the win9x fix when there are built issues with the Unicode version.

Fixed possible crash bug with card specific style options. By changing the set stylesheet it was possible for the option values to be matched with the wrong fields.
