Tendenci

* Fixed an error in corporate memberships import (Thanks evanspaeder)
* Added missing phone2 field to corp profile (The phone2 field exists on app, but was missing in CorpProfile model).

* Fixed links on the full settings list not being linked to the specific settings.
* Avoided using the same ud fields for cloned membership applications because same UD fields can't be re-used across applications.
* Resolved a permission issue on deleting unneeded membership applications (and corporate membership applications).

* Directory owners can view and edit their directories, but only admin can publish directories that are created with memberships and corporate memberships.
* Updated memberships to have email address take precedence over first name and last name when assigning a username.
* Added the link to directory listing, if any, on user profile and at the bottom of corp member profile.
* Added the link to corp member profile, if any, on directory listing.
* Updated post-install-checklist.txt for newsletters settings.
* Updated boto3 to 1.12.8 and django-ses to 1.0.3.
* Fixed the issue about pricing 0.00 not working for custom forms.
* Resolved the issue regarding custom forms showing page's nav menu instead of form's when a custom template is selected.

* Adjusted (or corrected) the files path for files uploaded in wysiwyg editor. For example, files uploaded in pages will go to files/page/, files uploaded in boxes will go to files/box...
* Files access of custom forms is restricted only to those who have the forms change permission rather than view permission.
