Implement OpenLayers.Layer.Text class

[sderle]

The OpenLayers.Layer.Text class can be ported from the old ol.DS.TextFile class.

This will also necessitate bringing forward proxy.cgi from the Mk III codebase, and putting it in a new example/ directory.

Base class exists, however, additional data is not stored in any structure yet. I think that this is a case where the OpenLayers.Feature class could come into play.

Discussion on IRC led to acceptance of the following properties:

• lat
• lon
• iconURL
• iconOffset (points to upper left corner of bounding box for icon, relative to latlon)
• title
• description

The last two are used for popups, the middle two default to a 'base' MC iconURL, and the first two are rather obvious. So far, the first three are implemented.

Should description be named content or a similar name instead? It should probably also be able to be either plain text or HTML.

This feature is implemented and committed.
