Refactor bookmarks code a bit from upstream, specifically fixes #627

Adds some initial work for displaying symbolic icons for bookmarks (like
in the sidebar) but no actual implementation yet.
Fix typo: recenly -> recently

Simplify button event handling for nemo panes

There doesn't seem to be a reason to handle button events both in
nemo-notebook.c and nemo-window-pane.c, so move all relevant bits to
nemo-window-pane.c instead.

Don't switch the current tab on right-click events

This change makes sure to keep the active tab on right-click events to
make Nemo behave a little more akin to applications like Firefox or
Chromium. Considering that menu actions like "move to left", "move tab
right", and "close tab" were previously all based on the current tab,
this change is slightly more invasive than desirable since we have to
pass the target page number along to quite a few helper functions now.

Use python2 for our python scripts
actions: Don't accumulate callbacks in views.

Normal GtkAction life-cycle is to be destroyed once its action group
is destroyed.  Since we use a manager to keep these around (to prevent
reloading nemo_action files all the time, we need to disconnect the
'activate' signals on these each time the menus are deconstructed and
reconstructed.

Fixes #658
