Validate property types

[jwadolowski]

It'd be great if cq_osgi_config could warn the user and correct simple mistakes in property types.

Use cases:

• true (boolean) is expected, but 'true' (string) was used
• string was used instead of 1 element array
  • WRONG: 'htmllibmanager.processor.js' => 'min:gcc'
  • RIGHT: 'htmllibmanager.processor.js' => ['min:gcc']

Correction should be optional and controlled via cq_osgi_config property.

not sure if allowing mistakes is a good idea, instead leaving a comprehensive error message which helps the user to easily fix his mistake sounds better to my opinion.

Allowing mistakes is definitely not a good idea. On the other hand converting 'true' to true is not a big deal and maybe warning should be enough.

Either way, types have to be validated to avoid idempotence violations.
