since it seems that it was lost

- Issue 858: Class template misses "uses:" clause'.

- Relicensing:

Added check for negative to Character>>value: and a test case

Removed: - StandardFileMenu class>>oldFileFrom:withPattern: (no senders on any pharo image, the only one that appears is a sender to the instance message of same name) - Form class>>rgbMul (no senders) - ExternalStructureInspector (no references) - ServerDirectory class>>transferServerDefinitionsToExternal (no senders)

The rest of changes are from Yoshiki changes in Squeak relicensing (reverted to clean versions or reimplemented)

Then Stef did a pass to fix again uniclasses left over and changing notify: semantics
