Optimizations and comments

Changed C style bracketed comment to C++ style (better for syntax
highlighter)... Optimized Timer setting to only set timer once,
not a maximum possible of three times in a row. Simplified wind
times cut off at 11 (snip off end); added new variable and changed
name of other to simplify code understanding. Optimized 305 processing
by putting getTimeUpdates up front.
Optimized code and removed excess spaces

Removed extraneous and useless spaces; optimized note card processing
slightly; replaced excessive llGetTime() calls with a single call.
Moved list of scripts to top of script for easier maintainability
and added LinkListen script for development users.
Optimized Prefs proc and rem LinkListen from list

Optimized the processing of preference settings considerably;
removed LinkListen from list of critical scripts to check as
it is an optional developer script.
Minor fixes, comments. Fixed winding down

Key was not winding down; fixed in Main: predictive timer setting
seemed to be failing.
