fix backtracking bug in 'Nfa.getMatchesInRange' (we were passing the wrong value instead of 'strIdx' in the recursive call to the loop function)

small change similar to previous commit: in search-list.sml's 'backtrackFull' function, always check if the position is at the correct string before checking if we are at the place where the search should continue

pass regression test by modifying 'SearchList.backtrackRange' function. The modification that worked was swapping two if-statements around: first we check if the string position is 0 (and loop to check the previous string if so); in the else case, we check if the searchPos <= 1 (which signals for us to exit backtracking). Swapping the order of the if-statements means that, when we exit the loop, we always exit with string that is at this position.

in BinSearch.equalOrMore and BinSearch.equalOrLess, return ~1 if no item is found, for the sake of less ambiguity in usage. Functions that call these have also been adapted.

add backtracking functionality to search; when we find a partial but incomplete match, we want to start looking for a match from ('idx + 1'), where 'idx' is the index we started this failed search at.

instead of clearing the search list when we delete, build a small part of it by searching through a small part that is likely to be visible on the user's screen, which gets rid of flickering effect and makes it look like the search list is not rebuilt from scratch

in search-list.sml: fix 'delRightFromHere' and 'delLeftFromHere' functions which joined newHd with left/right, rather than the tl, and therefore added new numbers to the list, which is incorrect behaviour. Fixed this by using joining with 'tl' rather than left/right. In build-search-list.sml: make fromRange function return tuple instead of an instance of app. Finally, in app-update.sml: progress towards refactoring 'helpRemoveChr' function to map and delete from searchList as desired.

fixed two issues related to insertion in search-list.sml. First issue: in top level 'insert' function, we called 'insLeft' if new value is greater than first value on right, and we called 'insRight' in the opposite case; this is backwards. Second issue: in base cases of 'insLeft' and 'insRight', when we have reached the end of one side of the list, we used to return the same list we got back instead of adding the new value to this end of the list; this is now fixed.
