Sanitize `state_dims` before use as loop variable

The overloaded `inspector` method in `RigidBodyWRLVisualizer` was
passing `state_dims` to the parent method as a row vector. The method in
`Visualizer` was then transposing that before using it as the loop
variable in a for loop. Since for loops loop column-wise, I've replaced
the transpose with a reshape to ensure that the variable passed to the
for loop is a row vector. Fixes #23.
Add class `RigidBodyVisualizer`.

Now both `BotVisualizer` and `RigidBodyWRLVisualizer` descend from this
class. It contains the nicely overloaded inspector method that respects
joint limits (this used to be in `RigidBodyWRLVisualizer`).

use addpath(fullfile(pwd,'..')) instead of addpath('..') because having '..' in the path generates loads of warnings. (matlab finds files that it thinks match builtin file names, but it's actually just finding it's own builtins)
