Allow configuration for retryLimit

[alias-mac]

It would be really helpful to allow a config param in karma.conf.js for retryLimit for browser crashes.

It would avoid us to wrap the grunt or karma call in a command like:

$ for i in `seq 1 3`; do grunt karma:ci; test $? -ne 3 && break; done

command.

I don't see any available configuration in http://karma-runner.github.io/0.12/config/configuration-file.html, but I do see it in the code a possibility to pass it:

karma/lib/launchers/retry.js

Line 3 in 9e0e385

var RetryLauncher = function(retryLimit) {

Could we make this setting available in config file?
Thanks!
