Distribution name should be treated case insensitively

[neilb]

If someone changes the case of a module, and that module is used as the basis of the distribution name, then PAUSE handles it largely correctly. MetaCPAN will treat them as different distributions:

I first released this with the module called Acme::NameChangeTest. This resulted in this line in 06perms.txt:

Acme::NameChangeTest,NEILB,f

And in 02packages.details.txt:

Acme::NameChangeTest              undef  N/NE/NEILB/Acme-NameChangeTest-0.003.tar.gz

I then changed it to Acme::NameChangeTEST, and those two entries became:

Acme::NameChangeTEST,NEILB,f
Acme::NameChangeTEST              undef  N/NE/NEILB/Acme-NameChangeTEST-0.004.tar.gz

I came across this while working on sorting out historical problems with changes of case. Historical cases like this resulted in multiple entries in the CPAN Index, but PAUSE doesn't do that now.

Guessing you're using CPAN::DistnameInfo to pull the dist name from the filename, but not then canonicalising the name.

A "real life example" is Tuxedo by AFRYER:

This will hopefully go away soon, as I'm working through cases where case-changed package names appear in the CPAN Index multiple times.
