Turn attrs into an object

[nippur72]

When a tag is compiled, attrs are stored as a plain string and later at runtime they are processed with the walkAttributes function (during the mount event).

I suggest to move attribute parsing into compiler, outputting attributes as a plain javascript object (key-value pairs) so it's easier and faster to process them at runtime.

@nippur72 , you are right and I have it in my TODO for the next version. It is one reason for riot.tag2, avoiding breaking change.

[aMarCruz]

maybe in v2.4, which also will include the remotion of __ for boolean attributes. I need write code to handle these changes in riot.tag transparently.

I also would love to see this feature landing in riot@3.0.0

[GianlucaGuarini]

the attributes can be spreaded with v4.0.0. <p ...{attributes}>. I am closing this issue
