added /dotnet-configuration parameter for electronize start command

[dmitrya1979]

if your .net core project has several configurations use /dotnet-configuration parameter

electronize start /dotnet-configuration MacOsRelease

[GregorBiswanger]

Please set /dotnet-configuration as an optional parameter for electronze start.

Maybe better if we can optionally store the configuration in the electron.manifest.json? Also have the possibility to store different electron.manifest.json here. This would simplify the organization for different environments considerably.

As example:

• Create a additional manifest file: electronize init /manifest test
• Start the app with your additional manifest file: electronize start /manifest electron.manifest.test.json
• Build the app with your additional manifest file: electronize build /target win /manifest electron.manifest.test.json.

This seems to be related to #324

The start and build commands are related and they should support similar arguments. Either someone updates the PR 324.

I would say we close this PR and if someone is willing to implent it, the PR 324 way would be better IMHO.
