This patch enables math expression evaluation for most of the text input
controls in pcbnew.
NEW: pcbnew text input controls are able to evaluate simple
mathematical expressions, including distance units (e.g. 5.0+(2*1.2mm)).
* Use "Close" in the file menu of every main frame window instead of the
mismatch of the terms "Close", "Exit", and "Quit".
* Change the terminology in the Pcbnew graphic text edit dialog to match the
module text edit dialog.
* Improve the layout of the Pcbnew graphic text dialog.
* Fix some wxPrintf parameter type assertions for 64 bit time_t.
* Fix all (at least I think I got all of them) duplicate menu accelerator
characters.
* Fix assertions in Eeschema when editing net labels, electronic rules check,
and plotting.
* Fix assertion when opening PCB calculator.
* Fix assertions in Pcbnew when changing footprints in footprint properties
dialog and adding or editing text.
subclass DIALOG_SHIM support.
Tried dialog_drc but it has nesting problems due to use of DRCLISTBOX, which
needs to be put into its own header file to untangle.
