Sort sql.qrc when generating, emphasize script

Sort sql.qrc when generating, emphasize script

Modify the update SQL resource script to version-sort output and
batch append it to the sql.qrc file.  This improves readability in
'git diff' output, and might slightly improve performance, too.

Move UPDATE_SQL_RESOURCE.sh to SQL/updateSQLResource.sh, making it
easier to find, right next to the other SQL management script.  This
required a few changes to the logic.

Document the new behavior in upgradeSchema.sh, keep the manual
instructions in case the script doesn't work.

Comments, comments everywhere.

(I really wish I would've known about this script earlier...)

Resolves GH-268.
