Merged node and area for theatre.

A few things from bus window round Sloane Square.

Traced buildings from Bing following recent visit.

This landuse is not correct (various visits), removed it.

Fixed earlier change: I spotted this building.

Made landuse more generous.

Traced buildings from Bing following recent visit.

Buildings and POIs spotted along Highgate Road. I will next trace building outlines from Bing.

Keepright: fixed almost-junction.

Keepright: fixed tag typo.

Keepright: added restriction type. (the only possible one given the street layout)

Keepright: connected pedestrian area to surrounding roads.

Keepright: removed spurious extra 'from' from turn restriction.

Keepright: added road crossings at Piccadilly Circus from local knowledge and Bing. The footways are only added separate from the roads in this small area, but could be extended.

Keepright: you can get onto this pedestrian area from the streets to the north and southwest, so connect it for routability. (Bing plus local knowledge)

Keepright: this little bit of footway is also part of the pier (Bing plus local knowledge).

Keepright: removed malformed and incorrect turn restriction. (St Paul's Churchyard does not have a junction with Distaff Lane; later on there is a junction but that has its own restriction.)

Keepright: this is a real junction (Bing plus local knowledge), so tagged layers to match up.

Keepright: the nonstandard 'restrictions' tag on this way is already implied by other tags, so removed.
