Add sorting by date created

## Prerequisites

## Feature
#### Is your feature request related to a problem? Please describe.
Sometimes I want to be able to sort files by the date created, rather than the date modified.

#### Describe the solution you'd like
A way to sort by the date created.

In the "Sort by" context submenu, "Date" should be split into "Date modified" and "Date created". In List view, Files should retain its current behaviour of showing only the "Modified" column for the file's date if using any sorting option that isn't "Date created". However, if sorting is set to "Date created", a "Created" column showing the creation date of files should be shown in place of the Modified column.
