Modify line endings in the ride editor

On mac systems, when copying data from excel and pasting into the ride
editor GC would complain about the data ranges not being the same size.
This is a result of the fact that excel mac terminates lines with a CR
(\r) rather than a NL (\n).  This patch changes the behavior so that we
check for all three commonly occurring line endings CR, NL and CRNL.

fixes #135
