import-radiostations
--------------------

Imports xml data files prepared using Dream's excellent radiostations hack (vb.org thread 152037)

Install the import-radiostations.xml plugin in the usual way.

Admin pages gain a new command "Import RadioStations", which prompts for a
xml datafile and a parent category into which to perform the import.

This extra follows the normal LDM standards, which is that duplicate entries are not created
in your database.  Consequently you can re-import the same file several times but this will
not create additional copies of the entries.

default-radio-stations.xml is the standard datafile released in Dream's hack.

NB: Radio station urls usually have .asx filetypes.  In order for these to play correctly
within LDM, you must:

a) Add the asx filetype to vBulletin's attachments filetypes table.  You can do this via
vb/admincp/attachments/attachment manager or by using the add-mimetypes LDM extra.
If you do it by hand, the required mimetype information is:
  "Content-type: video/x-ms-asf"

b) Add the asx filetype to list of filetypes handled by LDM's Windows Media Player player -
LDM/admin/media players, include asx in the list of filetypes handled by WMP.
