Luke Ceddia b586eafd3b Integrated _BLINEINPUT into regular LINE INPUT for BINARY files
LINE INPUT will now use the faster method if passed a file handle
that has been opened FOR BINARY. As such, the _BLINEINPUT command
has been removed.

qb64.bas now takes advantage of this for reading from '$include files,
at least in Include Manager 1. Some tweaking of internal/source/main.txt
was required to get things into a sane state, so I'm holing off changing
the compiler any further so the auto-builder can make sure everything's
smoothed over.

Note: Everything should still compile as normal; I'm just being overcautious.

The {{KW|_DEST (function)|_DEST}} function returns the handle value of the current write page (the image used for drawing).
{{PageSyntax}}
:''result&'' = {{KW|_DEST (function)|_DEST}}
{{PageDescription}}
* The current write page is where all drawing occurs by default.
* The value returned is the same as the latest [[SCREEN]]'s handle when creating custom screen modes using [[_NEWIMAGE]].
* Keep the _NEWIMAGE handle values when you move to another SCREEN mode so that you can return to that screen later. You can go to another screen mode and return without having to redo the screen!
* _DEST return values do not change in legacy screen modes. The value will not help restore them.
