Fixed compatibility with wxWidegets 2.9.1.

Added hotkeys editor from David Turner, with a lot of enhancements and fixes
Added pins connections info in intermediate netlist for each compoment. This is redundant, but some netlist formats (ORCADPCB, PSPICE) are very easy to create with this redundant info.
