modified fsharpi that handles piped inputs nicer (Thanks John Wostenberg!)

# Beware this line must match the regular expression " (\/.*)\/fsi\.exe" when fsi.exe is fsi.exe.
# That's because the FSharp MonoDevelop addin looks inside the text of this script to determine the installation
# location of the default FSharp install in order to find the FSharp compiler binaries (see 
# fsharpbinding/MonoDevelop.FSharpBinding/Services/CompilerLocationUtils.fs). That's a pretty unfortunate
# way of finding those binaries. And really should be changed.

Note that you may need to update your path to mono
