Fix bug where Wiki pages that include a '/' were no longer accessible
### What does this MR do?
This MR fixes a regression that caused Wiki pages that included a '/' to no longer be accessible.
### Are there points in the code the reviewer needs to double check?
Are there cases that `wiki_helper.rb` doesn't handle?
### Why was this MR needed?
The upgrade from Rails v4.1.2 to v4.1.9 (76aad9b76e) caused slashes in a model ID to be escaped automatically. We can no longer use the built-in the URL helpers to generate the links for Wiki pages if we want to maintain support for slashes. There is no option to tell the formatter otherwise:

The Rails code in question is here:
https://github.com/rails/rails/blob/4-1-stable/actionpack/lib/action_dispatch/journey/visitors.rb#L159

Support configurable attachment size in Application Settings page
### What does this MR do?
This MR provides the ability to configure the maximum size of an attachment inside a note. A parameter has been added to the Application Settings page.
### Are there points in the code the reviewer needs to double check?
What should be done with the legacy note attachment validation? I added code to make the validation work with the configurable setting. I could see an issue where an admin lowers the limit from 10 megabytes to 5 megabytes, which could cause an existing model to be invalid.
### Why was this MR needed?
We often have attachments that exceed 10 MB, and it would be nice to be able to override the defaults.
### What are the relevant issue numbers / [Feature requests](http://feedback.gitlab.com/)?
See Issue #1258

Addresses #1347.
Untested since I'm in a bit of a hurry. Will definitely have time to test and add unit tests before the 7.10 release :)
