Documentation for prop naming (non-breaking)

Warnings appear with vue 2.0 in inspection: (when doing :useCustomSlot="true")

[Vue tip]: Prop "usecustomslot" is passed to component <Anonymous>, but the declared prop name is "useCustomSlot". Note that HTML attributes are case-insensitive and camelCased props need to use their kebab-case equivalents when using in-DOM templates. You should probably use "use-custom-slot" instead of "useCustomSlot".

Updating documentation to help others, avoid warning messages.
