Add borg check and rename options

Because we added borg check functionality, some of the Options have been
renamed:
-C -> -V
-E -> -e (as it is a sub)

-C: check
-y: --verify-data
-p: prefix or glob for check

Internal variables with CHECK have been renamed or changed to VERIFY

Borg -C without any extra parameters is equal to borg check.
-y adds the --verify-data and -p is a mix of the -P and -a options. If
there is a "*" in the option then -a will be used, else -P

Note that repair command has to be run manually. Run -C with -v
(verbose) to see the repair command structure.

borg check can take a long time on very large repositories.
