[#5] Guarantee the sorting order of the data

We do that simply by ordering (ASC) by every field that's being filtered. This
makes us independent on the order the data was loaded into datapusher.

Fixes #5.
Sort the x axis using the order the user defined the filters

We used to only sort the series. Then, say that we got data like:

```
date,region,value
2011,Pakistan,500
2011,Bagh,200
2011,Punjaab,300
```

And my chart is defined as:

* _series_: date
* _xAxis_: region
* _yAxis_: value
* _filters_: "Pakistan", "Bagh"

I would like the order in the x axis to be the same as I filtered. But as
previously we weren't sortering the x axis (just the series), they would end up
alphabetically.

This patch fixes it.

It won't work with horizontal charts, but as we're not supporting them yet,
that's OK.
