DL4J Javadoc: problematic package names

This may be an upstream package naming issue, but it seems that git can't cope with the same directory but different case:

https://github.com/deeplearning4j/deeplearning4j-docs/tree/master/api/v1.0.0-beta2/org/deeplearning4j/text/tokenization

```
c:\DL4J\Git\deeplearning4j-docs>git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)

modified: api/v1.0.0-beta2/org/deeplearning4j/text/tokenization/tokenizerFactory/package-tree.html
```

These are always marked as modified in git - I can't check out, reset, hard reset etc to fix this.
