[doprocess] Automatic process versioning

[AleksandarDev]

Processes should be versioned. Starting from V1...VN.

Process

When editing process version that already has process runs new version is automatically created.

• user has option to select which version is being viewed/edited
• only "Latest" version will automatically create new versions
• when editing old versions no new version is created
• creating new version takes all existing task definitions and transfers them as copies to new version

Process run

Runs are linked to specific process version and are versioned indirectly via linked process.

Nice to haves:

• migrate run to new version (if possible)
