Lots of code restructuring, fixing jshint errors, fixing variables accidentally added to global namespace, etc.
Removed some unnecessary markup
Removed unused digits
Moved Google Analytics to bottom of page
Cleaned up formatDate function and added comments to clarify use
Removed the check for input type=file since it is part of the html 4.0 spec and has been supported in Internet Explorer since ie4.  This should be available in ALL browsers.
cleaned up checkForURLParams function and added documentation
Removed addFilesForUpload function and coded directly into the submit function since it was only used in one places.
Updated the stabFormReturn function.  Converting the response to JSON was unneccesary since the response was already stored as an object and the properties we needed were directly accessible.  Also, accessed the appropriate form directly to reset it instead of a particular instance of the form that was passed to the function.  Also added documentation.
Updated the formResponse function.  Removed unneeded JSON conversion and create constant variables for symbol colors
Remove old and unused stabTestFormResponse
Merged appendOb and getSingleObs functions
Modified and documented the functions to submit and get observations from the NWAC api
Added documentation of getObservationById and addObservationToMap functions.  Also, added globals esri, dojo to jshint rules
Added NWAC api resource URL as a variable so we can easily change between production and development APIs
Removed error catching in resetForms function and changed to "if" statements instead of ternaries
Updated nwac api comment
updated the formReset function to operate on a form name string instead of a form object (this makes it a little clearer on what is happening).  Added documentation.
Form selector was missing quotes and ending bracket
Re-added the showCalendar function which was accidentally removed.
