+ Some components need to be run at the startup of mozilla or embedding - to 
+ start new services etc.
+
+ This interface provides a generic way to start up arbitrary components 
+ without requiring them to hack into main1() (or into NS_InitEmbedding) as 
+ it's currently being done for services such as wallet, command line handlers 
+ etc.
+
+ We will have a category called "app-startup" which components register 
+ themselves in using the CategoryManager.
+
+ Components can also (optionally) add the word "service," as a prefix 
+ to the "value" they pass in during a call to AddCategoryEntry() as
+ shown below:
+
+    categoryManager->AddCategoryEntry(APPSTARTUP_CATEGORY, "testcomp",
+                        "service," NS_WALLETSERVICE_CONTRACTID
+                        true, true,
+                        getter_Copies(previous));
+
+ Presence of the "service" keyword indicates the components desire to 
+ be started as a service. When the "service" keyword is not present
+ we just do a do_CreateInstance.
+
+ When mozilla starts (and when NS_InitEmbedding()) is invoked
+ we create an instance of the AppStartupNotifier component (which 
+ implements nsIObserver) and invoke its Observe() method. 
+
+ Observe()  will enumerate the components registered into the
+ APPSTARTUP_CATEGORY and notify them that startup has begun
+ and release them.
