Alias Categories

Build server aliases should use the IssuesAliasConstants.MainCakeAliasCategory and PullRequestsAliasConstants.PullRequestSystemCakeAliasCategory constants for defining their category:

[CakeAliasCategory(IssuesAliasConstants.MainCakeAliasCategory)]
public static class MyBuildServerAliases
{
    [CakeMethodAlias]
    [CakeAliasCategory(PullRequestsAliasConstants.PullRequestSystemCakeAliasCategory)]
    public static IPullRequestSystem MyBuildServer(
        this ICakeContext context)
    {
    }
}
