Some differences are due to difference between libraries being files
in symbol editor and directories in footprint editor, but this unifies
most of the rest.
It also dispenses with the save-to-library vs save-to-document distinction
in the GUI because it makes for too much variability in the GUI, was
implemented differently between the two editors, and isn't needed as much
anymore now that we have the highly visible infobar.
There was also an issue that the save-to-board icon occupies the same
location and has the same size/shape/colours as the Board Setup icon in
PCBNew.

Prior to this change the "Save As.." command would take a different action
based on the state of the editor which could be confusing. There are now
separate commands for saving the currently selected library or symbol.
CHANGED: The implicit save as menu entry which would save the currently
selected library if no symbol was selected or the current symbol to a
different library. There are now separate save as commands for libraries
and symbols to make it obvious what is being saved.
The accelerator strings really shouldn't be part of the translation,
and some translations have cause the accelerator keys to be incorrectly
handled. It is simpler to make it separate and just join them to the
translated string.
Make all accelerator modifiers use lowercased Ctrl instead of CTRL
to be the same as the other modifiers.
