New features in branch ublas_feature0010_ide_dev_support

Hello,

I've committed several changes in the branch
ublas_feature0010_ide_dev_support (I've not yet pushed them to ublas).
The changes that I've implemented are:

1 - Test programs are executed automatically once compliled.

2 - To compile tests and brenchs, headers files of ublas source code
are included.

3 - If ublas tests and brenchs are build with modular boost source
code, the header files of boost source code are included and its
libraries are linked.

4 - Created configuration.pri file to centralize the configuration of
tests .pro files.

I've tested the changes in Linux but they should tested in Windows and
MaxOSX systems before pushing the changes to ublas. The repository to
clone is https://github.com/jdurancomas/ublas.git.
