* Add third list control with library names.
* Add button to toolbar to select filter by library name.
* Add bitmap for filter by library name toolbar button.
* Remove custom UI colors from list controls.
Because now there are 2 formats, board backup files extensions are .brd-bak or .kicad_pcb-bak instead of the old .000 extension, depending on the initial file format.
Kicad manager: shows now svg files in tree files.
Pcbnew: fix incorrect printing (board out of page) when creating drill map in postscript format ( noticeable mainly for small boards)
* serious code cleanup (remove duplicate code)
* shows (option in 3D preference menu) the copper items (tracks, zones...) in 3D, using 35 microns copper thickness.
However, because there are a lot more3D data to show (roughly 4 times more), this is slower.
This is *a work in progress*, so some features are missing, and/or could be modified.
Mainly keepout zones are not yet exported to autorouters, and pads are not taken in account.
Some code cleanup in polygon.*
Should allow Pcbnew code easier to change and Gerbview code more understandable and easier to maintain.
Code cleaning (remove dead code, add comments).
Minor other enhancements.
Pcbnew:
* graphic_item_properties_base.fbp * dialog pad edit: make some strings more easier to translate.
* global pad edition: fix a bug that change pad position instead of pad size (round pas only).
Eeschema:
* fix a bug: new created wires were not alwaes shows until the screen was redrawn.
More about code refactoring in connect.cpp: RecalculateAllTracksNetcode() is 50 times faster with a board using 27000 tracks
Use right icon in pcbnew for load board and new board.
* Replace use of wxICON by new icons declaration.
* Remove unused files.
* Fix filenames inconsistencies between old and new icons.
* dialog_erc handle variable size icons in erc matrix.
