(Port) Port Pixelorama to Ubuntu Touch (#517)

* Add support for creating Ubuntu Touch click packages.

The clickable directory contains the files necessary to create a
click package designed for Ubuntu Touch, a community-driven Linux
distro for mobile phones as an alternative to iOS and Android.

A new CI script has been added to create the packages, which is
copied over from one of my other projects. Please change this to
suit your needs.

A new custom feature "clickable" has been added to the project
settings to allow customizations for the Ubuntu Touch platform.

+# Building Ubuntu Touch click packages
+
+# Ubuntu Touch Click Packages
+
+The following subdirectory contains the necessary development files to create a click package of the app for [Ubuntu Touch](https://ubuntu-touch.io). Special thanks to @abmyii and the UBPorts team for making this possible.
+
+## Build instructions
+
+1. Start by exporting the pack file with the preset "Clickable (package only)".
+2. Copy the resulting .pck file from the `dist/linux` directory (or wherever you specified the Linux export) into the `Misc/Clickable` directory and rename it to `Pixelorama.pck`.
+3. Copy the `pixelorama_data` directory from the root into `Misc/Clickable`. 
+4. In the terminal, run the following:
+
+```
+$ cd Misc/Clickable
+$ clickable build
+```
+
+The resulting click file should be present in the `build` directory inside of `Misc/Clickable`, which can be installed on an Ubuntu Touch device by copying the file over.
+
+### Multiple architectures
+
+Note: To build for different architectures, pass in the `CLICKABLE_ARCH `environment variable.
+
+For example, to build for armhf and arm64:
+```
+$ CLICKABLE_ARCH=armhf clickable build
+$ CLICKABLE_ARCH=arm64 clickable build
+```
+> Note: It is recommended that you provide packages for at least the `armhf` and `arm64` architectures.
+
+### Important gotcha: File loading and saving
+
+Due to AppArmor policy restrictions, you are not able to save to anywhere outside of the user data directroy.
