[evolution/wip/webkit-composer: 88/372] Make (Un)indent actions work

[Tomas Popela <tpopela src gnome org>]

commit 4752fc4ce41ed3ce54e7786919f5e2c5eb5f733e
Author: Dan Vrátil <dvratil redhat com>
Date:   Fri Aug 3 12:25:35 2012 +0200

    Make (Un)indent actions work
    
    Sensitivity of Unindent action is binded to 'indented' property
    of EEditorSelection, so it's controlled automatically.
