Upload gzipped files

[mflynn-lanl]

Users would like to be able to upload files that have been gzipped. The GUI will have to be changed to not reject .gz files. The upload function in the API will need to be modified to check for files with .gz file extension, uncompress them and remove the .gz file.

The Javascript file that handles uploads, uploadr.js was modified to accept .gz files

The function upload in phame.py was modified to check for .gz files, open the file and write to another file without the .gz file extension and delete the .gz file
