bug: updates with aos 2

[twilson63]

Since aos 2 is a breaking change, to try to stay as backwards compatible as possible,

• the blueprints should check for 2.0 features, before they use
• we should create an alias module 'ao' that points to '.ao'
• should make sure false and nil print to the output
• enable modules to be found by names
• stretch goal to implement .dryrun which will work like load, but performs a dryrun - it would be cool if this would work on --watch modules too
