Git commands fail for %Developer user if git not on path

[isc-pbarton]

If "git" is not on the path, and instead the full path to git is specified through git-source-control configuration, all git commands will fail for a user with just the %Developer role with a NOTOPEN.

The reason is that the "git bin path" configuration setting is stored in a global in the %SYS namespace, so you need access to that global. A %Developer will get a PROTECT error trying to access it.

Fix will be:
Change SYSNamespaceStorage to use ^%SYS instead of ^["%SYS"]SYS
Add an installation step that will migrate settings from the old global to the new global
