This makes it possible to use Qt's QSortFilterProxyModel::lessThan option for
completions where it doesn't make sense to priorize matches starting with the
entered string, e.g. for URLs. In return, we get a *much* better performance
(several seconds when opening the completion).

This adds PyYAML as a new dependency.
It adds the following new commands:
:session-delete <name>
Delete a session.
:session-load <name>
Load a session.
:session-save [<name>]
Save a session.
:wq [<name>]
Save open pages and quit.
And the following new settings:
general -> save-session:
Whether to always save the open pages.
Before this, we always resized the completion when the mainwindow was resized.
If the statusbar is hidden during the resize (ui -> hide-statusbar is true), we
got an invalid calculated QRect for the completion, causing the update to be
not applied at all - so the completion showed up incorrectly.
With this change, another resize is done when the completion is shown - at this
point it's certain the statusbar is visible. Also we only update it while it's
shown - it doesn't make sense to always adjust its size when it's hidden
anyways.
