Version bump to v1.1.4
Version bump to v1.1.5
blank LWRP, to start
use variables, instead of attributes, so this can work with a provider
use the lwrp to configure the default server
fix typo, add notification
the behavior now matches the old recipe without the lwrp
add support for some more config variables
add attribute to allow skipping the default server conf
support plugins
describe the new LWRP and attribute
next time I'll run the tests *before* I commit...
make foodcritic happy
