Make this usable

Sync the version of GNUstep compiled to that shipped with Hopper,
and update the patches to track the changes upstream.

Rework the install location. The SDK now installs into the user's
`ApplicationSupport/Hopper` directory, and drops a symlink to the
`GNUstep.sh` environment setup script into `$HOME`

+# Introduction
+
+This is an update of the Hopper
+[Linux SDK](https://www.hopperapp.com/blog/?p=150) to match the
+versions of libraries shipped by more recent Hopper builds.  
+
+# Usage
+
+```
+git clone https://github.com/ckuethe/HopperSDK-Linux
+cd HopperSDK-Linux
+./install.sh
+
+. ${HOME}/hopper-gnustep.sh
+# go about your plugin development business.
+```
+
+When the build finishes, the SDK will be installed in
+`${HOME}/GNUstep/Library/ApplicationSupport/Hopper` as
+`HopperSDK-${SDKVER}` and `gnustep-$(arch)`. Additionally a symbolic
+link to `GNUstep.sh` - required to set up some environment variables
+to compile plugins - will be installed at `${HOME}/hopper-gnustep.sh`.
+On a multiuser machine, each user will need to run this SDK installer.
+
+# Notes
+* On recent Ubuntu (17.04) `libxml2-dev` `libgnutls28-dev` `libxslt1-dev`
+`libgcrypt20-dev` are to compile GNUstep base
