BC breaks?	no
Deprecations?	no
Tests pass?	yes
Fixed tickets	-

• Move logic for Search::show to new classes.
• Improved handling of Map HTML output by adding a new prepareInputParams method for search output classes. This allows forcing some criteria so the location fields are included in the Map view
• Added showPreSearchDisplay method for search output classes to handle showing widgets before the search input form such as the mini dashboard shown for the HTML output for Tickets
• Unified the method naming for displaying/outputting the results
• Moved the remaining method logic left in Search

Is there a reason to keep errors in new methods names? datas is not correct, new methods should be correct I guess :)

Also, I think tests should be added on new class/methods (well, when it's possible, I keep in mind Search is a very huge part); doing that later would be a too huge job.

@cconard96 please rebase to fix tests.
