Add a newer bootstrap button library

The newer version has a radio group of buttons which I need for displaying the
views, or at least I need that functionality and I don't want to reimplement
it. I've included it as a separate file without replacing the old one since I
don't know what will break. However, this is messy and should be changed. I'll
keep this file since it makes things work until Anton and I decide what to do,
weather to update, reorganize, or reimplement functionality.
Add controls for each type of motif
Update controls to use newest library.

This fixes some bugs, most notably it actually displays 2D structures now.
However, there are still some problems.

1. The buttons that should toggle do not, for example consider the IL, HL, and
Click/Select buttons. This appears to be due to the fact that we are using an
outdated version of bootstrap-buttons.js. However, I am not going to upgrade
this yet. Without the newest version they do not show the expected toggle
behavior.

2. We cannot display 3D structures. This has something to do with a complaint
inside jmol.js, which I have no control over. The cause may be else where but I
haven't isolated it yet.

3. The circle is too small.

4. It does not start in airport view for those structures that have an airport
view.

Overall this commit is an improvment so I will add it.
