Evol/link in ref

[gwilherm]

As @The-Lum suggested in #635 (comment)

This change puts the main link of a reference box before the : in a sequence diagram

Feel free to discuss any point

Before:

@startuml
ref over A,B : [[mainlink{tooltip}]] inline ref with [[link{tooltip} links]]

ref over A,B
  [[mainlink{tooltip}]]
  with multi line text and [[link{tooltip} links]]
endref
@enduml

After

@startuml
ref over A,B [[mainlink{tooltip}]]: [[firstlink]] inline ref with [[link{tooltip} links]]

ref over A,B [[mainlink{tooltip}]]
  [[firstlink]]
  with multi line text and [[link{tooltip} links]]
endref
@enduml

Gives:

Whole area link leading to "mainlink"

Many thanks for cleaning the code and the syntax.
I think that it somehow break ascending compatibility, but since the impact is very limited, I think it's still ok, since the result is more consistent.

Thanks also to @The-Lum for syntax suggestion.

Hello @gwilherm, @arnaudroques, and all,

For a to-do list....

• It is plan to do the same thing (adding topurl, ...) for group, alt, loop,...?

Sorry I am not currently a good java developer.
But I can help to populate the to-do list...

Regards.

Well, coding is not the only way to contribute.
And your contributions in documentation, forum and to-do list are really helpful!

So populate the todo list is really a good idea. Giving short examples is also a very good point.
