Merge pull request #131 from dobbymoodge/check-sources-bugs

<oo-admin-check-sources.py> Bug 1025147, give repo disable instructions according to repo subscription type
<oo-admin-check-sources> Add --subscription-type and --report-all options

`--subscription-type` allows the user to specify the entitlement system
instead of relying on detection

`--report-all` Tells the tool to report all problems found. Currently
it disables the `--fix` option if specified
