patch: alpha

This patch allows users to change the opacity of the background. Note
that you need an X composite manager (e.g. compton, xcompmgr) to make
this patch effective.

Notes:

        * The alpha value affects the default background only.
        * The color designated by 'defaultbg' should not be used
          elsewhere.
        * Embedding might fail after applying this patch.

Changes in 0.8.2:

        * The internal method for querying X visual is changed. St will
          respect the visual of its parent window, allowing it to be
          embedded easily.
        * Opacity value is now typed in float.
        * -A option is added to allow changing the opacity value without
          compiling.
