commit fdda0e2e9844b34700aff331ca462f78fb0aac2e

    Rewrite some build tasks and imporve build
    
    * SetDataAtBuildTime.cs: Dropped in favor of SetValues.cs
    * SetValues: A generic build task that sets values for variables in files
    before the actual build. Much like during autotool's configure pass.
    * PrepareAuthorsFile.cs: Formats the AUTHORS file's content at the repo
    root to be properly processed by SetValues task.
    * CopyrightInfo.txt: Provides copyright info for processing by SetValues
    task.
    * BuildBinScript.cs: Dropped. Not needed anymore.
    
    * Tasque.targets: defines the tasks used in build.csproj.
    * build.csproj: uses the new tasks now and imports Tasque.targets.
