moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

input.Makefile: SVN: add: verify: Also ignore *.xlsx

inputs/input.Makefile: SVN: add: verify/: Added *.xls to svn:ignore

Moved tnrs table from public (schemas/vegbien.sql) to its own TNRS schema, which is created by a new .TNRS datasource. Note that .TNRS is included in the automated testing, but not yet in the import.
