Flipper Zero app template

Assume the root of this repository is the root of an application folder.

(Eg. If the repo is named my-cool-app, then it will exist as applications/my-cool-app within the flipperzero-firmware repo)

With the exceptions of:

• Dotiles (any file/folder name starting with a .) are ignored.
• The assets folder is overlaid on top of the firmware repo's asset folder.
• The lib folder is overlaid on top of the firmware repo's lib folder.

All other subfolders will stay in the application's root folder. A Flipper Application Manifest file must be present as application.fam in the root directory.
