LIVEOAK-65 Simplify multi config mapping
  - Removed @ConfigMapping in favor of @ConfigProperty on method parameters
  - @ConfigMappingExporter no longer requires a value as it is only placed on a single method for exporting all config
  - Updated Config usage by RootResource implementations to follow new pattern
LIVEOAK-51: Move less files to /less folder and add maven less plugin to
compile as CSS in /css folder. Changed references to CSS instead of LESS
at index.html
