Some missing constants in WlanAPI

[IgitBuh]

I'm actually not sure if this repository is the original source for this library. But it seems to be the most advanced version I found and it's the first search result, so I'll give it a go...

I've noticed that some constants are missing. Could you please add them to the project?

nduL2cmn.pas:
24:
  NDU_L2_NOTIFICATION_SOURCE_WLAN_HNWK                = $00000080;


nduWlanAPI.pas:
15:
  NDU_WLAN_PROFILE_GET_PLAINTEXT_KEY = $00000004;

622:
  NDU_WLAN_NOTIFICATION_SOURCE_ONEX = NDU_L2_NOTIFICATION_SOURCE_ONEX;

  NDU_WLAN_NOTIFICATION_SOURCE_HNWK = NDU_L2_NOTIFICATION_SOURCE_WLAN_HNWK;

I'd also like to suggest to replace all tab characters with two spaces. Using tabs is bad as they lead to strange effects during navigation and when copying parts to a different location. This can easily be done with search and replace.
