- The multiplier used when computing percentages in the SAR ProcFS
parser has been raised to 100000 to reduce accuracy loss

- Fixed a couple minor bugs arising when only one column is selected
in the stat file
- Fixed a bug in the SAR parser

- Added the htVal parameter to the copy constructor

Change perf-plugin implementation: Instead of duplicating sensorGroups per CPU only one group is used with duplicated sensors

- Fixed a few warnings introduced in the latest ProcFS commit

- Virtual threads can now be automatically aggregated for procstat and
sar groups
- the htVal parameter is the number of physical threads; corresponding
virtual threads are determined via modulo arithmetic
- Minor changes to AnalyticsController in collectagent

- Auto-publish is now case insensitive with respect to the <sensor> and
<group> patterns
- If an invalid pattern was specified (missing <sensor> clause) the
configuration is aborted
- Checks for the uniqueness of sensor and group names have been
temporarily dropped as they interfere with templates and entities
(until we find a good solution for MQTT topics)

- Added some more indentation to make the configurations more readable
- Fixed one more warning in dcdbquery

- Boolean configuration options now all accept "true" and "on" keywords
- Cache interval and thread count parameters removed from the command-line
interface for consistency; these can still be set in the config files
like all other parameters
- global.conf file renamed to dcdbpusher.conf for consistency

- Added a 'common' directory where all shared code has been placed
- Analytics package has been moved out of dcdbpusher, now has its own makefile
- Some renaming here and there for uniformity
