Disambiguate tape_engine_8A as tape_engine_0x8a

This will revisit #2358 to avoid filename collisions on Windows, Rubymine
environments, etc.

This collision is killing me too. OS X + good old git command.

Okay, landing. :P

Verification:

• See that ./modules/exploits/windows/brightstor/tape_engine_8a.rb is removed.
• See that ./modules/exploits/windows/brightstor/tape_engine_8A.rb remains.
• See that ./modules/exploits/windows/brightstor/tape_engine_0x8a.rb is added.
• Running module/exploit/windows/brightstor/tape_engine_8A from msfconsole produces the appropriate deprecation banner:

[!] ************************************************************************
[!] *                      This module is deprecated!                      *
[!] *              It will be removed on or about 2013-09-26               *
[!] *       Use exploit/windows/brightstor/tape_engine_0x8a instead        *

@wchen-r7 is the git error recoverable? I don't hit this on Linux, obviously.

No, it will always tell me either I have tape_engine_8A.rb modified, or I have tape_engine_8a.rb modified. Doesn't matter what I do. I'm not messing w/ this right now because I'm in the middle of a module.
