Standardize on "remove" vs. "delete"

[jidanni]

Consider saying "remove" instead of "delete"
Throughout the interface it would be better
to make it clearer:

Remove (a layer): removes it from the layer stack. (what JOSM does.)
Delete (a layer): removes it from file system. No getting it back. (Not
what JOSM does, thankfully.)

Delete (a point, line, etc.): in this case yes it really is gone. No
getting it back. So "delete" is OK to say here.

Not all layers are linked to a file on the file system, so delete is sometimes the correct term (data will be lost if not saved).
