Let's use make's implicit variables.

Removed compiled files
Configured travis to build and deploy the executables

The executables are rebuilt whenever the utils/ directory is modified or when the commit title contains [exec-build]. I have also added an option to disable rebuilding the documentation with the [docs-skip] directive. When [docs-skip] is in the commit title the documentation is not updated. This commit also makes travis preserve the history of the gh-pages branch.
Merge pull request #17 from caffinatedmonkey/build

Move Executables to gh-pages
