this fixes combined_editor in extra fields.

Catch all exceptions in onPaint functions, because otherwise we show a message box. Message boxes while in a paint handler lead to a crash on win32.
Made a CATCH_ALL_ERRORS macro containing the common catch statements.

changed function name (exportCard -> includeCard), because it better describes what the function does.

Added German translation.  Also only up to date as of 0.3.6b.

Added remove_duplicates flag to sort_list function;
Fixed documentation of <size:> tag

Fixed: Incorrect comparison operator for AColor caused Scriptable<AColor>s to not be updated when only the alpha changed.

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.
