[PATCH v5] Thunderbird: fix appp.sh format problems

[Marco Stornelli <marco.stornelli@gmail.com>]

The current script has got the following problems:

1) It doesn't work if the language used by Thunderbird is not English;
2) The field To: filled by format-patch is not evaluated;
3) The field Cc: is loaded from Cc used in the commit message
instead of using the Cc field filled by format-patch in the email
header.

Added comments for point 1), added parsing of To: for point 2) and
added parsing of Cc: in the email header for point 3), removing the
Cc: parsing from commit message.

v5: fixed comments by Junio C Hamano
v4: create a tmp file to allow correct perl parsing
v3: parse only To: and Cc: in the email header, fix some comments
v2: changed the commit message to reflect better the script implementation
v1: first draft
