Remove classfile from root of tigris jar

[mitchelkuijpers]

For some reason there is a JSONStringEscapingInputStream.class file in the root of the jar of tigris 0.1.1. This breaks using cheshire or tigris in an OSGI bundle. Could you cut a new release without the classfile in the root of the jar?

Huh, I didn't do anything special when I generated it, I'll have to check into this and see if I am able to remove it.

I just built 1.2-SNAPSHOT and there it doesn't occur. Maybe before releasing you forgot to clean the target folder?

[dakrone]

@mitchelkuijpers okay I released 0.1.2, can you give it a shot and see if it fixes the problem for you?

@dakrone it now contains Build-Jdk: 11 in the META-INF/MANIFEST.MF which fails because we still need to run on JDK-8. But it fixes the other problem.
