Adds a basic completion model implementation around the global browser
history and registers that for the open command.
Modifies WebHistory to add an __iter__ method and to use a dict instead of a
set to store an entire HistoryEntry for each archived item instead of just the
URL. Brief tests showed that the lookup time for set and dict are very
similar. They are at least on the same order of magnitude. Testing membership
of a list on the other hand, as was the case before a set was used, was four
orders of magnitude slower on my machine.
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.
