fixed a hashing problem with mixtures & h_arrays.

Note: if there are problems with Mixture()s in the near future they
might be caused by this change of inheritance. Mixture clearly should
inherit from h_array, but it didn't, and it's possible that the change
could have unintended consequences.
don't do that.
updated bootstrap command line args to allow all _noise functions.
Changed LEG to have fewer symmetric pure strategy equilibria. Also added a noise function that mixes normal, bimodal, uniform, and gumbel.
Appended _game to names of game generators in RandomGames.py.

This makes it easy to export all of the available random game
generators as RG.game_functions. Noise functions can also now be
accessed as RG.noise_functions. I used this to make all game and noise
functions available as command line options in Bootstrap.py.

I also added .1 to the default noise spreads in Bootstrap.py to conform
to Ben's experiments.
fixed some bugs in evaluators
small fix
ObservationMatrix should cast to SampleGame until bootstrap is separated out
erase old games in sequential main
minor
being dumb and pushing changes to move them to another computer
moving to yaml based configuration
removing results from the repository
deleting results
plot takes multiple files
stuff
temp
don't know why it's ignoring my ignore
