Work on loading old (deprecated) patches.
More error tolerance in Store, related bugfixes. Patch port adding (threading) bug fixed (made event blocking). Better PatchView cacheing. Moved generic things from engine to util (shared) Bug fixes, features, etc. git-svn-id: http://svn.drobilla.net/lad/ingen@142 a436a847-0d15-0410-975c-d299462d15a1
