Support Java 8

[rgrigoryev]

I try to use @Multiline on Java 8 building with gradle and 'net.sf.gapt' plugin, but see in logs following:

warning: No SupportedSourceVersion annotation found on org.adrianwalker.multilinestring.MultilineProcessor, returning RELEASE_6.
warning: Supported source version 'RELEASE_6' from annotation processor 'org.adrianwalker.multilinestring.MultilineProcessor' less than -source '1.8'

Do you have plans about supporting Java 8?

Those warning messages are benign, i.e. multiline works with Java 8 (Mightly!) , but should be be removed.

I have figured out how to suppress the Warnings. Apply this patch:
