update bootswatches, add classic theme, reset
find-replace renderer for environment check table

I think this got lost in a merge because it's almost identical
to the renderer above it.

I really need to file a bug about the difficulty of overriding
these two renderers and add it here as a comment.
delete a few rules for non-existant tables

These rules are unecessary, either because the table doesn't
exist or look better without it.
buttons should look like button-default by default
use extend, not mixins for creating form-group row

Slightly less CSS, slightly more self-documenting
remove hardcoded color for login page details

This hardcode's #111 for a couple of things on the login page
which messes with bootswatches. I was going to move it to
the custom bootswatch but I'm not sure it's correct. It seems to be
making a link not look like a link, but I'm not sure why.

And the label tex should already inheret the correct color.

make dropdowns looks more bootstrappy

The block drop-downs look like cheap imitations of bootstrap
menus, so this is a first go at making them a bit more authentic
looking.

remove any RTL rule that can be autogenerated

Also add noflip comment marker for things that shouldn't be
flipped. That leaves ones that change background images mostly.
Merge #156
newly renerated moodle.css
move rtl only CSS to their own files

Also added a switching mechanism based on the current language,
note that this will then cache RTL or LTR until the next theme
change so it's not suitable for sites using both directions.

There's still an issue with the columns on the front page, I
think there's some Moodle mechanism for RTL that's fiddling with
the block order and interfering with the basic Bootstrap grid.

edit: actually I think it was just the block swapping stuff at
the bottom of config.php that was causing that, looks better now
that I've deleted it anyway.
expand toggles RTL fixes

The rtl-css-flipper doesn't yet support the background: short
version to converting them to background-image, background-position
etc. and using absolute or percentage values, not pixel as they
are unflippable.
