Add test for an infeasible problem

[IainNZ]

Currently fails on ECOS 1.0.5.

It looks like in #16 that we can't upgrade, is that correct?

Not sure if its been fixed, I'm going to file an issue to see whats up.

Not until the win64 version builds and passes its tests without segfaulting.

For recording's sake, here is the test in JuMP format:

using JuMP
 import ECOS

 m = Model(solver=ECOS.ECOSSolver(verbose=true))
 @defVar(m, x)
 @defVar(m, u <= 0)
 @defVar(m, v >= 0)
 @setObjective(m, Max, x)
 @addConstraint(m, x == 3)
 @addConstraint(m, 8u + 9v <= 25)
 @addConstraint(m, u + v - x == 0)
 solve(m)

 println(m)

Problem is confirmed to be in ECOS

worth a rebase?

mmm looking at it now
