Style/theme implementation

[elad]

Initial implementation of style/theme parsing, following your input.

Experimental and guarded by the cellStyles option (default: false)

Addresses issue #36

@elad good start!

I added a few test files. In particular, take a look at https://github.com/SheetJS/test_files/raw/master/cell_style_simple.xlsx -- this has a few column styles as well as row styles, block styles and individual cell styles. Do the colors roughly line up with the sheet?

After doing all of that, please squash to one commit :)

[elad]

I just realized that I only took care of fgColor and the test file had grids that required bgColor as well. After adding it, I think the colors match.

I think I managed to squash it... Had to merge master though otherwise it wouldn't let me push.

@elad Your log still shows 8 commits. You should only end up with one commit. You might need to do a git rebase followed by a git push -f.

[elad]

And now?

[SheetJSDev]

Now we are down to one :)

Clean up the git message (fortunately this is just git commit --amend)

[elad]

Done. :)
