Major cleanup of many icons (started as a simple effort to tweak libedit and modedit icons)
Ref: https://lists.launchpad.net/kicad-developers/msg32860.html
* Each application icon has been updated
* Consolidated icon "modifiers" across many icons
* Replaced confusing arrows with "load" and "save" icons
* Slight code updates to reference correct icons
* Consolidate multiple representations of single icon type(s)
* Mainly the wxDialog that was opened when the wizard is created is now no more created by the wizard frame CTOR. On some W.M. it created a serious issue related to the way Event Loops are managed. Now the user has to call it by the toolbar tool.
* 2 settings not saved in config are now saved.
* a few other minor enhancements
* better icon in footprint wizard frame
Remove a few #define relative to the wxWidgets 2.8 version, no more supported.
