Specify class directly next to node

[notramo]

Class definition is too far from node:

A --> B[node text]

classDef myClass fill:#0f0,stroke:#333,stroke-width:3px;
classDef anotherClass fill:#ff0,stroke:#333,stroke-width:3px;

class B anotherClass
class A myClass

I think it would be easier to understand:

A.myClass --> B[node text].anotherClass

classDef myClass fill:#0f0,stroke:#333,stroke-width:3px;
classDef anotherClass fill:#ff0,stroke:#333,stroke-width:3px;

The syntax with a single dot is intuitive but unfortunately breaks backwards compatibility in flowcharts as for instance this graph would break:

graph TB
   176.123.34.56 --> 172.123.35.78

Instead I propose we adapt another delimiter, instead of '.' we can use ':::'
