Add if, else, and, or to module format

[kieranoreilly]

I've found quite a few use cases where if, else, and, or would be useful for module format

[sslava]

we could implement it as container module with conditional rendering

[sslava]

implemented conditional module it covers if & else cases

[sslava]

@kieranoreilly one question: the condition should depend only on the preset variables? or it is possible to change the condition value by triggering a switch control for example within a module?

[kieranoreilly]

Ah that is a great question. I think the long term vision is the later, but anything is better than nothing right? :D

[sslava]

sounds good to me :)

now it supports && || ! and variables from current form
