Feature request: TruffleContract.version

Issue

Due to the semantic versioning system going away especially with web3, I have been spending an inordinate amount of time lately on bugs related to breaking changes in dependencies, and not knowing exactly which version of truffle-contract is being used in any particular test makes this a lot harder.

In some cases, a bug appears with a later version of truffle-contract which is not present in an earlier version, but identifying exactly where the bug appears can be a challenge (especially when other code must be adapted due to breaking changes between corresponding versions of web3).

Steps to Reproduce

1. Follow the Pet Shop tutorial. (Optionally browse the source, including a review of package.json).
2. Optionally attempt to replicate successful behavior in a different dapp, and fail because the files src/js/truffle-contract.js and/or src/js/web3.min.js are different versions.
3. Attempt to determine the versions being used. As a simple example,
   console.log("web3 version: ",web3.version); (in the Pet Shop tutorial) produces api: "0.20.3" and more, in a response object.

Expected Behavior

console.log("TruffleContract version: ",TruffleContract.version); produces meaningful output other than undefined. If it produces a string like "4.0.12," one should be able to run npm install truffle-contract@4.0.12, look in node_modules/truffle-contract/dist and find an copy of truffle-contract.js or truffle-contract.min.js which is exactly the same as the one the client was running to produce that output.

Environment

• Operating System: Windows 10 Pro
• Ethereum client: N/A
• Truffle version: That's the key question. truffle version produces 5.0.12.
• node version (node --version): 9.3.0
• npm version (npm --version): 6.9.0
