Fixes for 7.10.2

See merge request !1804

Fix bug where commit data would not appear in some subdirectories

Fix issue where commit data would not show up in some subdirectories due to escaped slashes. For example:

https://gitlab.common-lisp.net/ecl/ecl/tree/develop/src/gc (now patched with fix)

The upgrade from Rails v4.1.2 to v4.1.9 (76aad9b7) caused slashes in a tree to be escaped automatically. Using a wildcard glob in the route prevents this behavior.

* Closes #1478, #1459
* Closes https://github.com/gitlabhq/gitlabhq/issues/9037

See merge request !581

Unescape branch names in compare commit

The upgrade in GitLab v7.9 to Rails v4.1.9 caused all branch names in the compare commit mode to be escaped (e.g. `/` to `%2F`). The compare mode would not always work when comparing against branch names with a forward slash.

Opted to unescape the branch name rather than use a wildcard segment to prevent escaping slashes because it seems like a more sensible URL. The slashes in this case aren't really represented by a tree structure (e.g. /compare/one/two/branch..another/branch/here).

* Closes #1399
* Closes https://github.com/gitlabhq/gitlabhq/issues/9105

Fix DB error when trying to tag a repository

Steps to reproduce: Go to a project settings, add tags, click on save changes

Observed behavior: Error 500

```
    PG::Error: ERROR:  column "taggings_count" does not exist
        LINE 1: UPDATE "tags" SET "taggings_count" = COALESCE("taggings_coun...
```

Ran `rake acts_as_taggable_on_engine:install:migrations`, removed the first
migration that created the `tags` and `taggings` table, and added the rest.

* Closes #1512
* Closes #1550
* Closes https://github.com/gitlabhq/gitlabhq/issues/6867
* Closes https://github.com/gitlabhq/gitlabhq/issues/9194

Fix Error 500 when searching Wiki pages

If a Wiki page turns up a hit in the search results, an error will occur:

```
Completed 500 Internal Server Error in 836ms

NoMethodError - undefined method `slug' for "test.markdown":String:
  app/helpers/wiki_helper.rb:10:in `namespace_project_wiki_path'

  actionview (4.1.9) lib/action_view/template.rb:143:in `render'
```

An unhandled String containing the name of the Wiki page would be provided to the URL path generator. This MR handles that case.

> This MR removes the access control for uploaded images. This is needed to display the images in emails again.
>
> The previous solution to base64 encode the images had to be reverted, because not all email clients supported it.
