Older nightlies with leading zeros in version string crash soljson

[cameel]

Originally reported in ethereum/solc-bin#21 (comment).

soljson-v0.4.1-nightly.2016.9.9+commit.79867f49.js crashes solc-js because the version it reports apparently does not conform to semver. solc-js should be able to handle that more gracefully.

This happens for --version and --bin. Probably in other cases too.

Repro

npm install solc
curl https://binaries.soliditylang.org/bin/soljson-v0.4.1-nightly.2016.9.9+commit.79867f49.js --location --output node_modules/solc
npx solcjs --version

Running the above produces the following exception:

TypeError: Invalid Version: 0.4.1-nightly.2016.09.09+commit.79867f49.Emscripten.clang

It must added to translate.js. Let me give this a look.

It seems based on semver rules a dot cannot be followed by a leading zero. As @cameel has observed.

By the way, I checked that nightly in Remix and it just fails silently - the compile button keeps spinning but on the console there is Uncaught TypeError: Invalid Version: 0.4.1-nightly.2016.09.09+commit.79867f49.Emscripten.clang.
