dart 4.1 deb on trusty has bad compilation flags

[scpeters]

I have observed very slow performance in gazebo with the dart 4.1 debian package for Ubuntu 14.04 Trusty. The revolute joint test world is about 50 times slower than on precise. We saw some of this same behavior in ros at this issue (fixed here).

@j-rivero pointed out that the 12.04 deb build log shows -O3 in the compilation flags, while the 14.04 deb build log does not show these flags. He also recommended the following patch:

diff --git a/debian/rules b/debian/rules

DART already uses compat 9 and debhelper (>=9).

I think compiling deb without -O3 flag is the reason of the slow performance as @j-rivero pointed out. The default build type in trusty deb build seems NONE so the compilation flags for release build, for example -O3, were not included. This should be fixed by setting the default build type to RelWithDebInfo in #219.

I believe this issue is fixed by #219. Please let me know if it is now. Thanks @scpeters and @j-rivero.

It looks good to me, thanks!
