project-wizard: bgo #700318 - Can't build a project whose name starts by a digit
glade: bgo #698705 - Add application/x-gtk-builder to supported mime types

With shared-mime-info version 1.1, a new mime type application/x-gtk-builder
was added. Add this to the supported mime types of the glade plugin so that the
document manager will automatically enable and use the glade plugin when a *.ui
file is opened.
terminal: bgo #699316 - Add option to disable terminal plugin

Since Anjuta could work without the terminal plugin, add an option to
disable it.
file-loader: bgo #700615 - Remove markup from title of Open With dialog

GtkDialog cannot use markup in their title.
dir-project: Fix compiler warning

https://bugzilla.gnome.org/show_bug.cgi?id=700767
git: Fix signal names in diff code
git: More signal name fixes in diff code
debug-manager: show registers pane

We need to call gtk_widget_show_all() on the disassemble and memory widgets
since anjuta_shell_add_widget() doesn't do that for us anymore.
bgo #694644 - Position of Locals and Stack panes not saved

Now the position of destroyed widget is kept in the GDL layout unless you
first remove the widget. This needs an update of GDL too.
