Lines should support different arrow types at either end

[devinnasar]

Proposal

Now that there are new arrow types (dots, and Xes), mermaid should support having different types are either end, such as dot-to-X, or X-to-arrow, etc.

Example

Support the following syntax:

• A o--x B
• A x--o B
• A <--o B
• A o--> B
• A <--x B
• A x--> B

etc.
