GitHub issue(s): #131

What does this Pull Request do?

Update Apache Tika to 1.19.1 for the following security vulnerabilities:

• CVE-2018-1338
• CVE-2018-11762
• CVE-2018-11761
• CVE-2016-6809
• CVE-2018-1339
• CVE-2018-11796
• CVE-2016-4434
• CVE-2018-1335

How should this be tested?

TravisCI should take care of it. If there is any language analysis scripts laying around, we should double check those.

Additional Notes:

This creates a build warning:

[WARNING] /home/nruest/git/aut/src/main/scala/io/archivesunleashed/matchbox/DetectLanguage.scala:33: warning: class LanguageIdentifier in package language is deprecated: see corresponding Javadoc for more information.
[INFO]       new LanguageIdentifier(input).getLanguage
[INFO]           ^
[WARNING] one warning found

Looks good to me! Out of curiosity, tested the .keepLanguages command and all still works.
