Convert hook_element_info. initial commmit

[andriyun]

Issue: #20

Initial commit done!
Need review:

• common things
• all js libraries added in dummy mode. Need to create issue to convert it
• process and preprocess methods added in dummy mode. How we will work on it?
• processGmapControl method is common for few elements. I don't understand how we can implement it in single place. Any idea?

Module for 7 version has hook location_element_info() which provide elements with process functions. Process function for location_element provides list of fields, like Location name, Street, Latitude, Longitude and other fields returned by hook_location_api.

But I see that you have created different elements for each field. We should have something similar. Please investigate module more detailed. This ticket should contain a class which will provide fields, and they will be available on the content type settings page
