Moved netnames (GAL specific layers) to a separate enum, to avoid saving/reading their settings from files.
Added a check for the number of PCB_VISIBLE elements.
Worksheet & general purpose overlay layers are visible by default.

Changed BOARD_DESIGN_SETTINGS::m_VisibleElements from int to long, to assure at least 32 bits length (without depending on the platfrom int size).

Add missing calls to Show( false ) to some main frames (Kicad, eeschema, gerbview), to force config saving when closing these windows.
Code cleanup and minor coding style fixes in footprint_wizard_frame.

The desire is to migrate designs *away from* case independence, and to create
designs which use literally (case specific) interpreted component names. But for
backwards compatibility, you may turn OFF this option if you really must.
(Remember that with KiCad using text data files, typically you would be better
off simply doctoring those files into a case literal state with a text editor
and move forward into the brave new world of case specificity. Also, BOM
generators may not work properly when you have this option turned OFF, the xml
export's referential integrity is broken on library part name. Hence the default
is ON now, as of 29-Jan-2014.

Add EDA_BASE_FRAME::Show() and call SaveSettings() only from there for all derived wxFrames.  Remove calls to SaveSettings() elsewhere.

github_plugin.cpp: in error message relative to"cannot get  zip archive...", line 496, make the sentence relative to http GET command not translatable
inside the full translated message.

Remove g_LibraryNames and all supporting infrastructure from pcbnew.  FP_LIB_TABLE is now local to major wxFrames.

Pcbnew: fix bug #1272714 . Code cleanup: use 2 different enums for pad shapes and pad drill shapes. Remove never used pad shape.

Increase boost download TIMEOUT to 10 minutes, offer a LOG_DOWNLOAD option for capturing download problems.

Fix not working + and - keys in layers manager.
Fix typo errors and modify some messages to make translator's life more easy.
