Fix sbt's compiler interface for 2.10.0-M1

fix-sbt-compiler-interface.sh

#!/usr/bin/env bash
# This is very hacky remedy to following error people using sbt
# and 2.10.0-M1 release of Scala are going to see:
#
# API.scala:261: error: type mismatch;
# found   : API.this.global.tpnme.NameType
#    (which expands to)  API.this.global.TypeName
# required: String
#		sym.isLocalClass || sym.isAnonymousClass || sym.fullName.endsWith(LocalChild)
#
# This script fixes sbt's compiler interface so error presented above disappears.
# I believe it should be fairly safe to use because sbt ships binary
# interfaces for 2.9.x compiler so this patch wouldn't affect them.
