Project 3 - Game v0.4

Updated header styles for aesthetics.

Removed blow glow (outline on focus) from taStatus and taHistory
(readonly) textareas. Remove resize handle from taStatus text area.

Tested setting global variables using onload event and function.
Determined these variables need to be declared and defined outside
onload event function.

Changed instances of '...location' to '...loc' per best practices to
avoid browser issues.

Changed certain function names from 'btn...' to 'attempt...' in
recognition that functions may be invoked by actions other than buttons.

Changed history (debugging) text from 'Clicked: ...' to 'Attempt: ...'
to more clearly and accurately indicate application flow.

Changed function 'btnGoTxtCommand' to 'btnTxtCommand' to avoid confusion
with directional functions.

Changed function 'goTxtCommand' to 'processTxtCommand' to be more
descriptive and avoid confusion with directional functions.
