This PR will extend the functionality of the quicksearch to be able to provide results even for core fields (name, contact_id, external_identifier etc).

Currently, core fields are being skipped from processing and fallback to the internal autocomplete search.

Feature Request

It would be great to be able to add some CiviCRM Core fields that aren't a part of the default Quicksearch, such as Date of Birth.

Here is a PR that does the following:

• Fixes some minor issues when basic/custom fields are not already registered in the database and the form configuration page is rendering, resulting in an error

• Increases list of displayed customfields from 25 entries to 1000 in the configuration page (current limitation was 25 customfields)

• Prepopulates the basic fields during extension installation and do a basic.

• Menu creation is being removed from the hook that was activated during installation, it's now residing inside hook_civicrm_navigationMenu.

Default search by Name/Email doesn't work because the api call Contact.getlist is not working properly when sort_name is the input field criteria

Normal behavior of quicksearch is when multiple results match the criteria, when [ENTER] key is pressed, next page is Advanced Search with the quicksearch criteria populated and the results displayed already.
This is working with basic fields, but not with custom fields. No criteria is set in Advanced Search and all Contacts are displayed as results
