Bug fix #2311

File name (40) and dirname (80) were too short in sequence data. Made it
compliant using defines FILE_MAXFILE and FILE_MAXDIR.
Also replaced all strcpy() and strcat() with strncpy/strncat, with the
defines in it.
Oh, also fixed plugin path length for sequence, was just 80!

Bug fix #2366

Restored old convention that made using SHIFT+CTRL while using button-
sliders go with 0.1 stepsize of CTRL.
(noticed too late that Chris Burt assigned to self... sorry!)
