Decide upon FA icons for edit/delete/etc

The theming docs for the older icon system (https://docs.civicrm.org/dev/en/latest/framework/ui/#older-icon-system) says that most are 'to be decided'…

"The following non CRM-specific icons are available:"

Icon	Replacement
edit-icon	To be decided
delete-icon	To be decided
dashboard-icon	To be decided
user-record-icon	To be decided
inform-icon	fa-info-circle
tip-icon	To be decided

While this older icon system is being phased out – replacing these icons from JQueryUI to Font Awesome needs agreement on which FA icons should be used. If the docs specify this then extension developers can follow the same patterns.

A suggestion for these, following from the pointers here which covers some but not all of these:

Icon	Replacement
edit-icon	fa-edit
delete-icon	fa-trash
dashboard-icon	fa-th or fa-home
user-record-icon	fa-id-card
inform-icon	fa-info-circle
tip-icon	fa-lightbulb-o
