[Module-build-general] META.yaml -> META.yml

[Ken W. <ke...@ma...>]

Hi,

In a small sign that the Module::Build interface is still 
alpha-ish, I've just changed the name of the 'metafile' it 
creates from META.yaml to META.yml.  Schwern pointed out that 
this will play better on filesystems with 8.3 naming conventions.

If any external tools (CPAN, CPANPLUS, etc.) are reading this 
file, they'll have to start looking for the newly-named one.
