this removes a lot of obscure parsers, and leaves us with the basics.
This includes at least all of the formats listed on
https://github.com/elastic/elasticsearch-mapper-attachments/issues/163
I will start adding tests for each one of these document formats,
and take it as it goes and see what trouble we run into.
Closes#163
Many of the tests were not running, or did not check the exceptions.
I renamed all tests to meet *Tests* so they run, and assert exception messages.
Also because we must (currently) invoke tika with additional privileges, I added
the security logic, and fixed unit testing to call our static method directly.
This must be package private for security reasons, i simply put everything in
org.elasticsearch.mapper.attachments package.
I upgraded tika to the latest, so we are up to date, and removed logic around
tika == null and old locale issues.
