added php-cs-fixer for PSR2 checks
use makefile for lint, whitespace checks
do not run lint on the makefile itself, only on php files.
"--" = end of options; "*.php" glob
got this from http://www.kernel.org/pub/software/scm/git/docs/git-grep.html
always terminate successfully when running "check-whitespace", "check-fixme". else travis will run forever..
added phpunit.travis.xml
make sure that php-cs-fixer is the last in line
removing unused stuff
adding travis build status of master branch to readme
removed "repositories" section
enable coverage reporting
removing make test, this is for local usage
