file share support (#328)

this change adds a serve command to the zen CLI. This can be used to establish links to a set of files which may be served to clients via the project store interface:

```cmd> zen serve Lyra/WindowsClient d:\temp_share\StagedBuilds\WindowsClient```

with the appropriate changes in UE you may then start an instance of the runtime and have it load all files via the remote file connection:

```
Lyra\Binaries\LyraClient.exe ../../../Lyra/Lyra.uproject -pak -basedir=D:\temp_share\StagedBuilds\WindowsClient/Lyra/Binaries/Win64 -Mount=Lyra/WindowsClient
```
