Update regex to match Version string correctly

I've noticed the version string does not get logged correctly after typescript version 1.0.1:

```bash
[13:24:33] Compiling TypeScript files using tsc version null
```

This is because the output of `tsc -v` now looks like this: 

```bash
message TS6029: Version 1.1.0.1
```

and the regex matcher is expecting the output to begin with "Version"

This change fixes the regex matcher to correctly match the version.

```bash
[13:24:54] Compiling TypeScript files using tsc version 1.1.0.1
```
