add KEY_ESC message type, and refactor app-update.sml to use it (always calls 'clearMode' function which always sets the app to normal mode, and sets the command strnig to empty)

do not use 'clearMode' in helpDeleteChr function, because we have 'buffer' and 'cursorIdx' parameters we would like to add to the app state before exiting the loop. Instead, go to end of loop by passing 'count' of 0

fix very minor issue in cursor.sml's 'helpViL' function (previously returned cursorIdx when non-line breaks is followed by non-line break, but now return cursorIdx + 1 instead which is the correct behaviour, because we want to move the cursor rightwards one position in that case

|
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.
