Added ability to supply device arguments as parameter to applications.

Change adressing #140 enhancement request.
It is possible to select rtl-sdr dongle:
-with device index through commanline parameter: `--args="rtl=1"` (where 1 is the device index). Caution: device index is not unique identifier and it changes on each connection of the dongle.
-with devices serial number, the commandline option in this case has following form: `--args="rtl=00000001"` (where 00000001 is the serial number).

NOTE: You can set the serial number with use of:
```sh
rtl_eeprom -s <serial_number>
```
