Add function to load user template via url parameter

[memartin]

I like to be able to put links to create new tickets on certain (private) wiki pages. It would be great if I could add a GET parameter to that link to choose directly my template that should be used.

Examples:

• Link to create new Ticket from My Template "Template1"

  http://trac.local/newticket?template=Template1
  

• Link to create new Ticket from user template with characters to be encoded in its name ("My Template l")

  http://trac.local/newticket?template=My%20Template%201
  

• Link to create new Ticket from My Template, using other (template) parameters

  http://trac.local/newticket?template=Template1&my_param=anything&owner=myname
