lua latebound function update

return the nextfunction and nil instead of pairs it allows a faster
return to lua rather than calling the lua function
pcall(fnpairs) from c and returning the result back
into lua to kick off the search
yeah, no clue why I didn't realize that before..

testing in x86 and ARM..
its more RAM efficient to do the initial creation
of the stack in lua code for the __pairs functon
its not faster but being that its a one time hit per
iter creation the reduced churn alone should be worth it
along with a reduced peak RAM usage

fix bug where a failed module can not be reloaded

optimize filetol

fix potential bug in splash scroller when no break character is found
