Spelling, dd block size, improved feedback
Spelling, dd block size, improved feedback

No XML file stored for each cases has values. Output file is in format
from Data::Dumper. Misc. spelling fixes, create case window now appears
in middle of screen, changed dd to use bs=1M b/c the datastores default
to 1M block sizes(Should find the  block size by executing vmfstools
--query -h /path/to/volume and parsing output). Also since MD5 and SHA1
values are calculated, tried to give some indication as to which one is
currently being calculated by slightly changing the window depending on
which is being calculated  Added in elapsed time it takes each operation
to complete. Gives user about how long it takes to calculate hashes and
for dd to complete. These times are displayed and logged once the task
has completed. Updating in real time would require forking of the dd and
hash tasks which would require possibly major code changes this late
