Update for Theano v0.7.0 release

We were using the development version for as_op [1], but now the
current PyPI version for Theano (v0.7.0) includes this.  It also
contains the fix [2] for issue #660.

 The latest version of PyMC 3 can be installed from the master branch using pip:
 
 ```
-pip install --process-dependency-links git+https://github.com/pymc-devs/pymc3
+pip install git+https://github.com/pymc-devs/pymc3
 ```
 
-The `--process-dependency-links` flag ensures that the developmental branch of Theano, which PyMC requires, is installed. If a recent developmental version of Theano has been installed with another method, this flag can be dropped.
-
 Another option is to clone the repository and install PyMC using `python setup.py install` or `python setup.py develop`.
 
 **Note:** Running `pip install pymc` will install PyMC 2.3, not PyMC 3, from PyPI.
