I've checked with other screen widths as well, and it looks good all the time.

Automatically link commit ranges to compare page.

Closes #2103

Implemented as proposed in the last paragraph of the issue:

> We could do something similar to Ruby, where `1..5` means `1,2,3,4,5` and `1...5` means `1,2,3,4`: `..` means inclusive, `...` means exclusive. In our case, `sha1...sha4` would mean `sha2,sha3,sha4` (exclusive with regards to `sha1`) and `sha1..sha4` would mean `sha1^...sha4`, i.e. `sha1,sha2,sha3,sha4` (inclusive to `sha1`).

- `sha1...sha4` now links to `compare/sha1...sha4`
- `sha1..sha4` now links to `compare/sha1^...sha4`.

Fix editor in IE producing errors #1096

IE seems to handle form submission oddly. It gets fired twice - once from javascript and once from the form click, producing 2 identical requests and causing #1096.

Similar issues: http://stackoverflow.com/questions/14373800

Returning false from the click event seems to fix it and shouldn't cause any side-effects.

Ruby str_equal uses memcmp internally to compare String.
Memcmp is vunerable to timing attacks because it returns early
on mismatch (on most x32 platforms memcmp uses a bytewise comparision).
Devise.secure_compare implements a constant time comparision instead.

Normalize output to use:
- User name instead of username
- Include first line of title in message description
- Link to "Issue #X" instead of "#X"
