added a new Sequence Effect: Sweep.

this consists of 22 different ways to sweep from 1 strip to another. For you windows lovers: it's like "Blinds" in Powerpoint :)
- in the NKEY menu you can choose which type you want perform, vertical, horizontal, in/out etc. it's too much to decribe.

Credits for this go to Kent 'Sirdude" Mein who coded the sequence plugin I stole the code from.

To allow certain sequence effects to have settings, I also added a "varstr" void pointer to the Sequence DNA, that can point to a special struct for each effect. This is similar to how plugins are handles.

more neat effects to come....
