fix typo: Occurence->Occurrence (important for consistency, see previous changes!)

@monperrus

This PR is follow up to refactor: fix naming occurences (re-introduced) #2214
As you merged #2214, this one should be too.
This PR finishes partial fix from #2214

Previous discussion: #2206

... it is interesting how much work might be to fix one missing r ... :-(

It is even more - it looks like I forgot to rename:

• setMinOccurence method and its argument
• setMaxOccurence
• patterns

so I created this PR.

Because we cannot have pair:

• setMinOccurence (single r)
• setMaxOccurrence (double r)

this PR is required for consistency and to clean a mess. Sorry!

I think now we have consistent min/max methods & their arguments & correct patterns. Someone please take a look.

I am ready to merge.

It still concerns typo in patterns, @pvojtechovsky are you ok to merge?

[pvojtechovsky]

I am OK with merge. May be we should release Spoon then again to minimize amount of clients of that old wrong API.

I might release Spoon at the end of august if needed. Don't hesitate to open an issue if you feel the need.
