Save Venues

[SudoWatson]

Since our events only take place in 1 of 2 different locations, it's pretty annoying to have to reenter the venue name and address every time I create an event. Especially since one is in an off-grid location and requires me to go to a previous event, copy the coordinates, and then paste them in the new event, as I cannot remember the coordinates.
It would be nice if I could save venues, and then choose from a list of saved venues which one my event is at.

Sounds great.
After reworking the forms just comited in develop, Maps/Leaflet config has a space waiting in edit form.
We can now start with #5 Open Steetmap support.
I will work on #17 Readme next.

• Would be nice to have a hook for a "list of saved venues" (so you could aadd any data there.
• Adress data is stored in wp_osec_events table. To read from there we would need a "get list of unique Adresses from there". Maybe via ajax hook and a Search field UI?
• What UI Element we should use to be keep it scalable in case of really huge ammounts of Events/Locations?
