set template falanx version from Version msbuild property (#104)

remove hardcoded value, less maintenance

skip template integration tests on unix/mac, tests fails with

```
Error reading template from file: /ClassLibrary-FSharp/.template.config/template.json | Error = After parsing a value an unexpected character was encountered: a. Path 'symbols.FalanxJsonCodec.value', line 62, position 40.
```

so near the escape of double quote of all

```
      "value": "(FalanxCodecFormat == \"all\" || FalanxCodecFormat == \"binary\")"
```
