Layout tweaks in Launcher

-Removed All apps and Configure toolbar buttons
from Customization Drawer, removed Configure
button from All apps and added Market icon
to All apps
-Changed spacing of CellLayouts when scrolling
-Modified gap spacing in workspace layout
-Made workspace invisible in All apps but touching
the place where the workspace was takes you back
to workspace
