latest version is latest2.

Some problems at the moment, esp to do with starting/stopping and refreshing.

Might need to go back to start of today's version of this file and start again from there.
reverted to earlier version and altered total time div
some smallish changes, still having probs with the 'c' value displaying, but other than that, things are pretty good!
disabled 'reset' button when timer is running.
Still need to remove 'c' value and refresh page when reset button is pressed.
