remove todo-exception from 'G' (NormalMove.goToEnd) command. The todo was a reminder to implement a way to get the scroll line when moving to the end. We have that implemented now.

fix exception caused by resizing in normal mode: we were passing 'buffer' to the TextScroll function previously, but we were meant to be passing 'newBuffer'. We are passing 'newBuffer' in this new commit as we are meant to.

pull in new version of brolib-sml so that we can get bug fixes for LineGap.getLineNumberOfIdx, delete the TextWindow structure (which was previously used to get the start line to draw from), and replace previous usages of TextWindow with TextScroll.getStartLine. This enables us to scroll in a way tailored to the reimplemented TextBuilder (which do not wrap lines or characters)

implement smoother horizontal scrolling. If the new column is already visible without changing the previous scroll column, then don't change. If the new scroll column is prior to the old, then scroll backwards; else, scroll forwards.

fix bugs in implementing and using text buffer. Some functions did not save the drawMsg to the app's state, which we means we didn't draw in those cases. The text builder functions also drew cursors on characters even when the cursor is not at this position. Both of these bugs are fixed.

fix minor bug when deleting around (with motion like da( or da< or da) or da>). The bug was that, if the last character we delete with the highest index is also the last character at the end of this line, we deleted the range properly but placed the cursor at a linebreak. In this case, the cursor is meant to be a single character before the line break, and after this commit, we have this desired behaviour.

|
in normal mode, when we receive an event which we don't want to handle (like enter), we clear the app's mode and command history instead of simply returning the same app unmodified. This fixes a bug: say we pres 'f' to go to a character and then press enter. Before this commit, pressing a character after that 'enter' will go to that character. This is contrary to Vim, which resets the command history on an invalid command, and now we reset the command history too.
