[Feature] Fast enumeration for FMResultSet about fmdb HOT 5 OPEN

Isn't simple while ([result next]) shorter? :)

It's not that obvious.
I spent some time searching and reading main.m to find out that you have to invoke [ result next ] to read the first record.

In fact, I'm ok with while ([result next]) but it would be NICE to have Objective-C fast enumeration support.

To say it's not obvious is a bit dramatic. It's right there in the readme under "Executing Queries:"
https://github.com/ccgus/fmdb/blob/master/README.markdown

I've thought about adding fast enumeration in the past, but I didn't seen the benefits to it. If someone wrote a patch for it and came up with some nice examples, I would reconsider it.

My bad. Instead of the readme I've considered the "main.m" code.

Anyway, the semantic of FMResultSet seems a bit strange. It represents both a set and an iterator for it at the same time. And iterator semantic is closer to the one used in Java world. It's not similar either to ObjC fast enumeration or to STL style iterators.

If underlying SQLite API enforces this kind of behaviour - so be it.

I'll see if I'll be able to do anything about a patch. However, I'm a bit busy at the moment.
And @ccgus, thank you for a great library.
