New issue 114 by fintic...@gmail.com: Allow hiding left pane
http://code.google.com/p/gpick/issues/detail?id=114

When picking a palette from screen or image, the more space for the image,
the better. Hiding the left-pane(which is irrelevant to this task), allows
the GPick window to be much smaller, and also allows you to move the right
edge of the window offscreen while keeping the palette colors visible
(effectively reducing the space occupied by GPick to little more than the
width of a palette color).

A very simple demo of what this could be like can be achieved by simply
inserting a line `gtk_widget_hide(notebook);` after the
`gtk_widget_show(statusbar);` in uiApp.cpp.

This simple test shows a few things:
* the palette widget needs to be reparented, much as the notebook currently
is when the palette view gets toggled.
* Picking with Space no longer works (instead, it 'selects the current
palette item', an operation which has no useful effect when the main pane
is hidden). This is important.
* The 'Secondary view' submenu needs to be disabled when the main pane is
hidden.
* The 'Palette' toggle also needs to be disabled (it's pretty silly to have
a window that is just empty.)

^ actually, I take that back about the palette visibility. It is actually,
surprisingly, still quite useful as long as you can pick colors with Space
and/or Ctrl+P, and see the color count.
