ruTorrent: Upgrade to v5.1.4

# ruTorrent v5.1.4
**This release contains a critical bug fix for mobile devices. It's highly recommended to upgrade.** 
1. Rotating the screen orientation on a mobile device (with the traffic graph open) is fixed. 
    - It no longer explodes with JavaScript errors. This bug has been present forever.
2. A couple minor bug fixes for the `check_port` plugin are implemented.

# ruTorrent v5.1.3
**This is a recommended release for common platforms only**. It resolves a style issue with the DarkBetter theme. It's not required for individual users to upgrade this release, unless they use the DarkBetter theme.

# ruTorrent v5.1.2
**This is critical hotfix for mobile bug fixes. It's highly recommend to upgrade.** It fixes the top menu opening incorrectly. All desktop platforms remain unaffected by this issue. This hotfix adds further polish when using ruTorrent on your mobile devices!
