feature_addition : Added a mean squared loss layer to DNN with test case

Added mean squared loss layer "loss_mean_squared" to
DNN as requested in https://github.com/davisking/dlib/issues/152
Also added test case of a simple linear regression with one variable
that uses this layer.

increasing loss more robust.  Now it will never get into a situation where it
backtracks over and over.  Instead, it will only backtrack a few times in a row
before just letting SGD run unimpeded.

code.

is built as a stand alone library and what appears in the config.h file.

training_label_type instead of a single label_type.  This way, the label
type used for training can be distinct from the type output by the network.
This change breaks backwards compatibility with the previous API.

this frustrates Visual Studio users who want to compile dlib as a static
library.
