flogoapp build issues

[torresashjian]

In the new flogoapp build process there are a few small issues:

• flogo.json is not in the bin directory
• flogo.json does not have type id for root task
• flogoapp build adds flows.go to it even though it is not needed

• flogoapp build will copy the flogo.json to the build directory
• generated root task now has "type":1
• cannot reproduce creation of flows.go when executing build command

Issues fixed.
