This update fixes the following issues with nagios-plugins-zypper:

- update to 1.48:
+ handle updates of the software stack as cricital unless we get a fix for bnc#832605 (workaround for bnc#830658)

- change logic looking for ignored packages/patches:
+ use exact match, not just substring
+ check also for match of name-version in the ignorelist allowing to ignore specific updates

- update to 1.47:
+ return error if zypper is already running and blocking the refresh of the repository

- do not call openSUSE 13.1 discontinued
- do not call SLE11-SP3 discontinued
