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.
