Add checks for blocks operations and other changes
* Add ISCSIOPS and FCPOPS checks type similar to CIFSOPS * New -V option sets SNMP version (needs 2c for reading 64bit values) * New -I option return every time OK state (if you needs only performance data) * redesign help message and append examples * nagioscache files create only if check needs caching * each check has own *.nagioscache file (when I using multiple tests I get inexact values of performance data) * change version to 1.2
