bugfix: inputs/IRMNG/: renamed to inputs/.IRMNG/ so that this comes before TNRS, which depends on it (this is a metadata datasource, so it can start with "."). part of issue #940.
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).
bugfix: inputs/*/Source/map.csv: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table. the staging table column renaming is now used by all Source tables.
added inputs/IRMNG/, including runscripts to download the names. this is now the 2nd datasource after GBIF to use runscripts, and the 3rd after FIA/GBIF to use new-style import.
