Bump version to 2.0.4

Changes:
 - Remove floating versions
 - Disable myget feeds during a Universe build
 - Use package-specific MSBuild variables. Pattern = `packageId.Pascalize() + "PackageVersion"`, with a few exceptions.

 If you're planning to submit a pull request, and if it's more than a trivial fix (for example, for a typo), it's usually a good idea first to file an issue describing what you're proposing to do and how it will work. Then you can find out if it's likely that such a pull request will be accepted, and how it fits into wider ongoing plans.

+.SYNOPSIS
+Build this repository
+
+.DESCRIPTION
+Downloads korebuild if required. Then builds the repository.
+
+.PARAMETER Path
+The folder to build. Defaults to the folder containing this script.
+
+.PARAMETER Channel
+The channel of KoreBuild to download. Overrides the value from the config file.
+
+.PARAMETER DotNetHome
+The directory where .NET Core tools will be stored.
+
+.PARAMETER ToolsSource
+The base url where build tools can be downloaded. Overrides the value from the config file.
+
+.PARAMETER Update
+Updates KoreBuild to the latest version even if a lock file is present.
+
+.PARAMETER ConfigFile
+The path to the configuration file that stores values. Defaults to version.props.
+
+.PARAMETER MSBuildArgs
+Arguments to be passed to MSBuild
+
+.NOTES
+This function will create a file $PSScriptRoot/korebuild-lock.txt. This lock file can be committed to source, but does not have to be.
+When the lockfile is not present, KoreBuild will create one using latest available version from $Channel.
+
+The $ConfigFile is expected to be an JSON file. It is optional, and the configuration values in it are optional as well. Any options set
+in the file are overridden by command line parameters.
+
+.EXAMPLE
+Example config file:
+```json
