100fcore/app-update.sml done with functionality of getting screen to move (if needed) when cursor moves, including getting screen to move when moving to a new chr (in this commit)

fixed two issues. First is that an exception occurred when sometimes moving cursor forwards. Cause of this issue was that callee functions depended on LineGap being moved to start of line, but this did not always happen (and now it does always happen). Second issue was that moving cursor down did not scroll as expected when line wrapped. The reason for this second issue was that the 'getStartLineAfter' function did not increment 'startLine' value in loop when line wrap occurred. Both issues are now fixed.
