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.
