Improve dialog layout and fix UI policy issues with all of the dialog
boxes in the Gerbview and Pcbnew code paths.
Updated the use of component to footprint where appropriate.
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.
