beta 2

Second version as an early pre-release to let people download and test it without compiling the solution themself.

Some changes:

• new UI based of https://github.com/modularcode/modular-admin-html
• forms are now JS based instead of postback-based, which will allow better performance and cleaner code over time
• first version of validation in forms based of the providers
• bugs found along the way
