Add .get() and .getall() aliases

[redapple]

In quite a few projects, I've been using a .get() alias to .extract_first() as most of the time, getting the first match is what I want.
To me, .extract_first() feels a bit long to write (I'm probably getting lazy with age...)

For cases where I do need to loop on results, I added a .getall() alias for .extract() on .xpath() and .css() calls results.

I know there's been quite some discussion already to have .extract_first() in the first place, but I'm submitting my preference again.

+1, I really like this.

How do you feel about adding a getall in Selector class as well?
It's so annoying having to explain the differences between SelectorList and Selector.

[redapple]

@eliasdorneles , interesting. would Selector.getall() return a single-element list?

[eliasdorneles]

Yeah, that's what i was thinking. :)

@eliasdorneles , done!

[eliasdorneles]

Yesss!!
This is great, easier to predict which method to use (get always returns the first, and getall returns as many as possible for the given context), you don't need to think much before deciding which method to use.
Thanks @redapple !

Hey @redapple @kmike !
I think this deserves a 1.2.0 release, I really like these new methods, and there is also #74 (new feature) and #82 (bugfix) since the last release.
What do you think?

[redapple]

I'm all for it.

[redapple]

It would be ncie to get this one fixed also: #84
