Altered DropDown widget (#60)

* Altered DropDown widget: Added another mandatory path variable - selection value (depending on use case, one could prefer direct access to selection value rather than selection index); and another optional path variable - options (string variable to allow for dynamic change of options, as opposed to providing static list of options through arguments); and example with both static and dynamic dropdowns.

* Make second path variable optional, for backwards compatibility
Project overview
================
In order to target the widest possible range of programmable devices and keep efficient, Beremiz use C code as an intermediate language.
To be executed, C needs to be compiled. `GCC <http://gcc.gnu.org>`_ serve that purpose perfectly.
PLC program is expressed in languages defined in IEC-61131, including graphical languages. Thanks to PLCopen TC2, those graphical languages have a standardised representation, in XML.
To be continued.
