Documentation update

I've filled out the details of all the methods provided by this module now, after realising that most dictionaries don't provide any useful morphological information for analyse() or the two generate() methods to use! So, I've cut the synopsis down to just the methods that make sense for most people, and re-ordered the method details so de-emphasise the analysis side.

The module used to refer to "OO Hunspell" in some places and "GNU Hunspell" in others. Given that Hunspell doesn't refer to itself by either of those names, and OO has become LO for a lot of people, I've dropped the prefixes.

I've changed the "Copyright" heading to "License", to reflect what is actually being said there, and what seems to be common in other modules, and I've slightly changed the formatting in the "Authors" section because the E<> codes weren't working before.

I hope this all makes sense and it's something you'll like. Today, I've also had a look at the "Kwalitee" tests on CPANTS for the first time, and I've got a few other small improvements in that direction coming in the next couple of weeks, in case you want to delay putting out a new release (but that's up to you, of course!)

Cheers,
Paul
