Change the default checkout location to something more likely, though it

should still be customized by the user; add UID check; fix bug with
non-existent repo directories (thanks to Mauro for the even less buggy fix);
fix bug with a subshell that prevented sspm from exiting on one error - it was
meant to be a group command; convert the su block into a normal block; add a
couple more exclusions to the tar command to skip backup and tags files - and
throw a note into the ChangeLog so users don't get surprised by the repo
moving or having its ownership changed

   * Be more strict validating YES/NO configuration variables.
   * Add a KNOWN_ISSUES file - if you encounter a bug, check this file before
     reporting it to see if it's known and if there's a workaround.
+  * Modify sspm to be root-only and change the default checkout location. In
+    case it isn't obvious, this means the checkout will be root-owned if it
+    isn't already.
