Update GDAS INIT utility for GFS COM reorganization (#820)

Changes to the GDAS INIT utility's copy_coldstart_file.sh:

1. Rename SAVEDIR to SAVEDIR_MODEL_DATA (for the model directory).
2. Introduce SAVEDIR_ANALYSIS for the newly separated analysis
subfolder (where the abias and radstat ICs go).
3. Remove the enkf loginc.txt file (no longer need).
4. Moved SAVEDIR* variable settings into the copy_data function
(to reduce redundancy in the if-block since they are all the same
now for SAVEDIR_MODEL_DATA regardless of member/suite).
5. Add $MEMBER as an argument for copy_data so I could do item 4
(used $MEM within the function but can use $MEMBER if desired).

Fixes #817
