Improvement: Exporting GM effects

[PolishZeus]

This will be the second suggestion that I believe would make FG2 a stronger program. The others will be posted independently for consideration. I am currently using the 3.5 ruleset.

*An option to export effects would be great so passing the GM responsibilities wouldn't be such a hassle (as we up levels, we're all needing to remember to add new spells effects).

*The description under the tutorials on how to write a custom effect is really lacking. Perhaps update this to make it more clear?
