Build a tool that submits nodes to OSM

[wbprice]

Using format from spec issue:

id => node:id
title => tag:name
longitude => node:lon
latitude => node:lat
location => ? // (may no longer have relevance)
artists => tag:artist_name
url => tag:source
imageurl => tag:website_1
fullimage => tag:website
description => tag:note, tag:note_1 // if more required.

Will be useful for submitting nodes in flat file, and also for submitting new installations / images down the road.
