[tex-live] Install file of the TL should have unique name

[Denis Bitouzé]

Hi,

in order to install TL 2013 on Windows, I told a student of mine to
click on the 'install-tl.bat' file in the TL folder. But, as:

1. by default, Windows hides the files' extensions,
2. TL provides 3 'install-tl.*' files,

my student didn't succeed to run the install wizard as he didn't click
on the right file.

He brought his computer at the university in order I help him but
I couldn't figure out what was the right file to run. I had to change
the Windows config in order to make the extensions be displayed, to
finally detect the .bat file.

Hence, it could be nice that for the install file of the TL to have
unique name.

Best regards.
