Limit git clone depth to reduce clone time
Although the repository has been cleaned up significantly, many large files are still retained in the repo's commit history. Cloning the repository with the full commit history takes up around 1.2 GB of space and takes more than two minutes on my home connection, ~30 seconds on a VM hosted on our SURF private cloud.
Recommend cloning the repository to a limited depth for users that want to build a runnable jar only, or do not otherwise need much of the history. E.g. cloning the repo with a depth of 1 (the minimum) takes ~20 seconds on my home connection and 4 seconds on a VM, with the repo taking up ~286M.
