functions.php - update metadata and inserts sections to allow new override system via custom plugins for previous years. Now checks for CONSTANTs before making definitions.

Affected: gv_microgrants_custom_metadata_manager_admin_init AND gv_microgrants_register_postmeta_inserts

Both are now on priority 15 so that they run AFTER any default init actions.

Both now check a constant before doing their definitions so that an earlier plugin (like gv-microgrants-questions-2013.php) can define the old questions. GV_MICROGRANTS_METADATA_DEFINED and GV_MICROGRANTS_POSTMETA_INSERTS_DEFINED

Most recent questions are kept in the functions.php of this child theme to speed up development by having only one thing to update while working on a new site each year.
functions.php - update this year's questions for timeline to refer to 2014 and for budget to say 2.500$ instead of $4000
functions.php - update gv_microgrants_custom_metadata_manager_admin_init to remove proposal-video, proposal-audio and proposal-photos because they won't be used for 2013
