[RFE#1714] chore: build languagetool as modules

Languagetools language libraries are optional for OmegaT application.

Other information

dev-ML discussion suggests

There is about 300MB with dependencies. We change core dependnecies such as LanguageTools and Apache Lucene.

LanguageTool 3.5 takes 65MB, and LanguageTool 5.7 takes 129MB.

Would it be possible to download LanguageTools separately (from within OmegaT) ?

LanguageTool in not a core OmegaT function. A lot of languages do not have use for it.

For first users, we could have a dialog that says "if you use such and such language, install LanguageTool to have access to grammatical... checks" and provide a link.

Lucene is a core function but not all languages have specific tokenizers, so here again, it there is a need to download the whole thing, do something similar for users who could benefit from Lucene.

To allow download LT separately, #226 is required.

TODO:

I spotted a few typos.

Looks good to me now.

I found that a source distribution has unwanted library jar files. It may be caused by a filter of "*RuntimeClasspath" that may include dependencies of Gradle plugins such as SpotBugs dependency.
It breaks build process of source distribution.

This caused from dependency jStyleParser library. I'd like to fix the issue in another PR.
