Change number of keys/tags/relations for main page.•••This makes the tag cloud larger on larger screens. The tag and relation types
list on the left don't need as many items, because they are small boxes anyway.
Preparations to remove JOSM source.•••* in_josm will now always be 0.
* Whether a key is in the JOSM config or not will not influence
standing in tag cloud on main page any more.
Hopefully make keyboard shortcuts behave better.•••Use keypress instead of keyup events where possible. This might help with the
problem sometimes seen that hitting CTRL-R will load the "relations" page,
because it uses the "r" key as shortcut.
