2 new bundles:
- CommandBundle - Holds all global commands for the 'stc' namespace. Currently the only command is
stc:entity:update [--cachetoo].

- ContractBundle - Basic bundle files & folders along with bundle-integration config (bundles.yml). Currently the entity 'Contract' and its CRUD operations are functional, however the contract generator is not built yet. (@todo ContractGenerator). Also added web/documents for contract file generation directory & placed a firewall in the security.yml to allow access to those with ROLE_USER.
