Support for function "wrappers"

It would be cool if PSScriptAnalyzer had a way to support different "function keywords". For example when using PSake to create build files the build tasks are captured in a special kind of function like this:

Task Compile -Depends Clean {
   "Compile"
 }

The problem lies in the fact that the Compile "Task"/function is not checked by PSScriptAnalyzer. Maybe a possible solution would be to offer users a way to register other "function keywords" (like "Task" in the example).

首先檢查 PSScriptAnalyzer 如何識別標準函式關鍵字，以及 PSake 的 Task Compile -Depends Clean {} 形式是如何解析的。當使用者可以註冊諸如 Task 之類的替代函式關鍵字，且 PSScriptAnalyzer 能夠分析這些包裝後的函式時，這項工作就算完成了。
