added planning/meetings/BIEN conference call availability.xlsx (backup of Google spreadsheet)

planning/timeline/timeline.2013.xls: updated for changes made in the conference call: moved Data provider validations (spot-checking) to beginning since that seems to have been decided to be a higher priority than architectural changes

schemas/util.sql: combining functions taking anyelement params which could be text: take text param instead, so that other argument types (e.g. integer) will first be implicitly cast to text instead of trying to concatenate integers directly. this fixes a bug in the VegBank.stemcount_,stemlocation_ _join() of two integer pkeys, which first needed to be cast to text. anyelement was previously used so that other text-like types such as varchar could also be used, but varchar is implicitly castable to text so keeping anyelement should not be necessary.
