[oe] wget --content-disposition flag

[Maxim Uvarov]

Hello,

can we add by default wget --content-disposition flag? Github has 
releases feature and creates tarball for certain git tag. And tarball 
file name is for example v1.tar.gz.  But for html content right name can 
be used i.e. project-name-v1.tar.gz.

If it's possible to add this flag wget will downloads files to right 
file names:

Example:
wget --content-disposition

Thank you,
Maxim.
