Change "name" to "project_name" to meet requirement of FILE_DUMMY_APPINFO

It's probably not the best solution as we lost short_name/long_name (well, they were set to set value before).
A better refactoring would to correctly retrieve short_name, long_name from old PBL_APP_INFO and let them be used in FILE_DUMMY_APPINFO.

But this solves Hexxeh/libpebble#26
