Windows installer: update to LAME 3.99

[dinkypumpkin]

I have posted an update to the LAME build used by the get_iplayer 4.4 
for Windows installer.  I was forced to update the installer 
configuration because the LAME 3.98.4 builds were rather unfortunately 
removed from the upstream repository when version 3.99 builds were 
added.  This update should prevent error messages appearing when the 
installer attempts to download LAME.

NOTE: You do *not* need to update!  Of course, you may update if you 
wish.  Although still referenced in the get_iplayer script, LAME is no 
longer actually used.  It was left in the installer package as a 
courtesy for anyone who might have some use for it.  After this, I think 
it is headed for the chop.

How to update:

1. You *must* have previously upgraded to get_iplayer 4.4 for Windows. 
The automatic update does not work with earlier versions.  If you 
upgrade to 4.4 after reading this, you will already have the latest LAME.

2. To update an existing installation, just run the get_iplayer 4.4 
installer.  If you don't have the copy you originally used to upgrade 
get_iplayer for Windows, you can download a fresh copy here:

3. After you click through the first installer page, you should see a 
notice that an update for LAME is available to upgrade from 3.98.4 -> 
3.99.  Click through to the component selection page and you should see 
LAME automatically selected for installation.  You may still deselect it 
at this point, or exit the installer altogether.  If you elect to 
proceed, the installer will overwrite the current version of LAME with 
the new version.

Note: If you elected not to install some components when you upgraded to 
4.4, you will also see update notices for those components.  You can 
deselect them in the component selection page.
