Add a TeachOSM-specific page to the OSM Welcomer

[geomantic]

Add a page for specifically for teachers/educators to the OpenStreetMap Welcomer. Include:

• Why to use OpenStreetMap in education
• About TeachOSM and services for teachers
• Pointers to all the other stuff out there

Please add your thoughts.

This is a great suggestion @geomantic. I'm going to put this on my list of projects to contribute to.

I suggest that we consider adding this as one of the main resources on the redesigned TOSM Resources page.
