Wrong use of css width attribute with bootstrap

[culpinnis]

Issue

There are several misuses of the width argument in combination with the bootstrap framework.
For example in:

MetFamily/MetFamily/ui.R

Line 1090 in 6e0fc54

column(width = 6, style="width:50%",

This breaks bootstraps responsible design.

Steps to reproduce

Resize browser window.

The breakdown occurs too late (when the content is twice the button/column size).

Possible solution

Use a width of 3 instead of 50% 6 and a button style of width:100 to fit them into the column. This will preserve bootstraps ability to break the row when necessary.
