[bauss]

Just made a new release for v2.8.1

https://github.com/DiamondMVC/Diamond/releases/tag/v2.8.1

This release contain the following:

* Smtp mail support
* Virtual html elements (Useful for dynamic html generation 
without being textual. Ex. for backends)
* File upload/download management
* Validation such as credit cards, emails, files, types and urls.

It also deprecates all usage of "placeHolder", which has been 
replaced with "placeholder" ex. "addPlaceHolder" should be 
"addPlaceholder" -- in 2.9.0 any place with "placeHolder" will be 
removed in favor for "placeholder"
