Add file view to the options for project views

Report: https://news.ycombinator.com/item?id=10257695

In https://gitlab.com/profile/preferences under behaviour I want to be able to specify the File view as my default project view.

While we're at it why not include wiki's too http://feedback.gitlab.com/forums/176466-general/suggestions/9037822-add-the-option-to-set-the-wiki-as-project-view

And add Activity as an option to the default dashboard view: https://about.gitlab.com/2015/09/22/gitlab-8-0-released/#comment-2267957999

for the "Activity" option

AFAIK the "Activity" view was the default behavior in 7.x (you could see all activities in all projects right after logging in), and we got used to it.

for the "Activity" option. This is the most useful behavior, I guess.

I totally agree with @jampy81 and @boeserwolf91

The "Activity" option was merged in !1446 (merged).
