--------------------------------------

In with rev 1524443:
 - added custom analyzer OakAnalizer based on lucene's StandardAnalyzer plus an oak filter
 - copied over lucene's CompoundWordTokenFilterBase, added the option to skip the current token
 - added filter that splits aplhanumeric tokens on '_' and '.'
 - tests

> Following OAK-1007 where I switched to a ClassicAnalizer, I realized that it introduced some subtle changes in tokenization behavior.
> For example there's a twist if the token contains a number.
> From the ClassicTokenizer api:
> bq. Splits words at hyphens, unless there's a number in the token, in which case the whole token is interpreted as a product number and is not split.
> this means that a path token could be split either in 2 tokens if it has no numbers:
> {code}
> /parent/child => 'parent', 'child'
> {code}
> or just one if it has numbers:
> {code}
> /p12345/p23456 => '/p12345/p23456'
> {code}
> Also, I'd like to split alphanumeric tokens on '_' and on '.' as well.
