Enable valgrind when testing on travis

This will slow down testing but will detect pull requests that introduce memory
leaks.
Add test reporting to travis script
Fix travis script

It was broke because the ls command failed when no valgrind.* file were found
Remove -e option from travis shell script
Modify travis configuration to install valgrind

This should fix previous build failures

This is necessary to keep the build from 'erroring' since running the tests
with valgrind will take a long time
