iStat Menus 4.20

If `mkpath` must be done for the parent dir, then it certainly
must also be done for the child dir.
Add LingrRadar.app
rename class to `Cask::CurlDownloadStrategy`

To make room to use some of the other download strategies
classes provided by Homebrew, be explicit that we are currently
using only the curl class.

Bugfix Release for OSX Only: LyX 2.0.7.1 released.

February 1, 2014

We are pleased to announce the release of LyX 2.0.7.1. This is a
bugfix release that affects Mac OSX only. Users of other operating
systems do not need to update to this version, and no binaries will be
provided for other operating systems.

There were some issues with the menus in LyX 2.0.7 on OSX.
Specifically, "dynamic" menu items were lost, and there was a problem
restoring the menus from full-screen operation. Both issues are fixed
in 2.0.7.1.
