[Portland] [PATCH] xdg-email: Case-insensitive run_thunderbird

[Jack Bates]

I clicked the "Reply to: john doe (on-list)" link on this page [1] and 
was surprised that the new message that Thunderbird opened lacked a "Cc: 
debian-boot at lists.debian.org" header.

The problem is that the <hfname> in the mailto URL is capitalized (Cc=), 
which xdg-email currently ignores.

I confirmed that a mailto: <hfname> *is* case-insensitive [2], so this 
patch replaces "grep" with "grep -i" and "sed s/.../.../" with "sed 
s/.../.../i" in the necessary spots.
