* Docs: First pass at improving analyzer docs

I've rewritten the intro to analyzers plus the docs
for all analyzers to provide working examples.

I've also removed:

* analyzer aliases (see )
* analyzer versions (see )
* snowball analyzer (see )

Next steps will be tokenizers, token filters, char filters

* Fixed two typos
