Add missing -rdynamic flag to the linking of dcdbpusher
Fix double-free error when destructing a Template-Sensor

Finished rework of sysfs-files.
Adapted and improved various other involved classes.
TODOs remaining:
-adapting Makefile for automated compilation of librarys
-solving runtime errors when trying to run dcdbpusher with sysfs

Removed no longer required files from SYSFSSensor
Renamed SYSFS to Sysfs
Introduce Configurator-base class, derive SysfsConfigurator from base-class

Available values in queue are only published if their number is >= minValues

Further improve exception handling of stoll()
Add possibility to use spaces for the regex in the config if quotation marks are used

Handle exception thrown by stoll() if empty string is handed over
Rename defaultSensors to SensorTemplate in config-file

Outsourcing of sysfspusher.cpp into multiple classes is now complete

Minor fixes to SYSFSSensor

For the regex ERE syntax is used, the substitution uses regular sed syntax.
The field "replacement" was removed.

Sensors are now an own class as well.
Adapt Makefile accordingly.
It is now possible to define default sysfsSensors in the config.
See sysfspusher.conf for an example.
