Unfortunately we must force Composer minimum stability <= beta due to Parsedown 1.8 currently being in beta. Composer AFAIK can't decide this on a per-dependency basis...
- Separate Travis branch deployment and release deployment stages (also makes `deploy.sh` obsolete)
- Add `clean.sh` and `release.sh` scripts to allow users to create "release" packages locally
- Use `setup/*.sh` scripts to check and install build dependencies (like PHP_CodeSniffer, phpDocumentor and cloc)
- Use `create-release.sh` of `picocms/ci-tools` to create release archives
- Streamline script usage
Use the following to test Pico and to create a "release" package locally:
```sh
cd ~/My-Pico-Workspace/Components/pico
ln -rs ../ci-tools .build/ci-tools
. ./.build/ci-tools/init/local.sh.inc
. ./.build/init.sh.inc
phpcs --standard=.phpcs.xml "$PICO_PROJECT_DIR"
clean.sh
release.sh
```
