Title: IDEA-57875: Add Missing property quick fix

http://youtrack.jetbrains.com/issue/IDEA-57875
IDEA-57875 No quick fix to create property from a usage of unknown property in Ant

This brings back the features that were available in v9.
It should create a property as an xml tag in the current file or as a property if a build.properties exists.
If multiple build properties exist you get multiple intentions pop up as well as the option to just include it in the current file.
