Fixed reload bugs.

This fixes some reload bugs such as:
reloading in seconds rather than minutes.
Timer not correctly being removed (cause multiple reload instance timers
to be created).
Default values upon page load (text box is now default disabled when
first loaded).
timeoutId will always be "null" when first loaded so no need to clear
timeout.
Removed trailing spaces.
