Stop quoting all configuration options so that prefix is not always on

[ghoneycutt]

Without this patch, prefix could be set to "false" which is not a
boolean and gets interpreted as true. This could result in your branches
being prefixed with 'puppet_'.

@acidprime upgraded to 2.1.0 today and it busted my production environment since the environment name changed from production to puppet_production. Suggest updating the CHANGELOG to warn people not to use 2.1.0 and to use 2.1.1 or whatever you tag this release as.

@ghoneycutt good catch thanks for being the guiney pig, might want to put some condtional logic eventually so we quote everything but boolean.

Thanks Zach! Thought the same thing with making the quoting smarter, though I tried not quoting my remote and all is well since yaml will treat it as a string without quotes.
