Subject: [PATCH] Increased version to 0.7 because of new "advanced" sensor
 parsing (line 191) -Added following line edits info to comments at the top
 and increased version number -Line 193, modified sensor parsing to cut after
 the first '+' since all positive temperatures are preceded by a + and the one
 we want is labeled first -Line 211, reduced "verbosity" needed to see verbose
 info (was 2: -v -v) -Line 229-232, now checks if no sensor data was found and
 exits with STATE_UNKNOWN -Fixed 2 typos, one in output and other an in-line
 comment -Updated line numbers in previous version info lines in comments
 since my comments pushed the lines down
