Normalize .pure-table {th,tfoot} -> text-align: left?

[lkraav]

I'm running into default alignment peculiarities in situations where .pure-table tfoot th elements are browser-defaulted to text-align: center.

We already have `.pure-table thead { text-align: left; }.

I'm proposing this should include .pure-table tfoot, too.

EDIT not sure about normalizing at th level. Thoughts welcome.

I see no problem with it. As pagination got dropped out of 0.6, it may actually help when using tfoot as part of the pagination area.

@lkraav my only reservation was treating tfoot the same stylistically as thead. Does it make sense that they should have the same treatment?

Alternatively, I would be fine just having a tfoot selector that sets the alignment to left.

@lkraav thought about this more, this makes sense since you may have a large table that needs the headers at the bottom of it too. You provided a commit but no PR, do you want to open a PR?
