type mismatch initSettings
When I generate an app structure using `logue init myapp`, cd into that dir and then logue run the app I get:
```
kgs/prologue-0.3.6/prologue/core/beast/server.nim(24, 35) Error: type mismatch: got <Port, string, int>
but expected one of: 
func initSettings(port = Port(8080); bindAddr = ""; numThreads = 0; startup: Startup): Settings
  first type mismatch at position: 4
  missing parameter: startup
```
