FR: input-event-group

[AvshT]

In order to keep the template code effective and readable, I'm suggesting this rule, that will warn if there is misordering between input and events in the html template:

<some-componenet (someEvent2)="aaaEvent2()" [someInput1]="aaa" (someEvent1)="aaaEvent1()" [someInput2]="bbb" >
will rise the warning - "inputs & events should be grouped"
<some-componenet [someInput1]="aaa" [someInput2]="bbb" (someEvent2)="aaaEvent2()" (someEvent1)="aaaEvent1()" >

Hey @AvshT, I guess this is the same thing requested in #127, so I'm closing this. Feel free to comment if not.
