* check for if/loop/endif/endloop match in scripts
* check for brackets match (same amount of opening/closing brackets) at line load. skip corrupt lines
* some code cleanups
* implemented SCP database functionality (.scp files). (sounds familiar? :P )
* new DefScript command: "loadscp,name filename"
* added .def file: append.def. (wrapper to concat strings)
** -> note that the scp db has no real use right now, just some program internal stuff which will come tomorrow. soon i'll have a go at DefScript return values, useable e.g. to get data from the dbs.
