Extend USB 3G Dongle Support by updating libgsmme1c2a

[marsmensch]

Short:
The Debian (Squeeze) Package "libgsmme1c2a" can not handle responses by certain 3G USB dongles.

Long:
Huawei EM770 sends a '+CSMS: ,1,1,1' reply instead of the expected '+CSMS: 0,1,1,1'.
This triggers an exception in gsmlib's parser and makes gsm-utils unusable with this modem.

I can confirm that this bug is resolved by installing / backporting the "libgsmme1c2a" from Weezy.

Fix and Debian Bugreports are documented here:
vbouchaud/gsmlib#5

If upgraded, The Pwnie will support the following devices:

• EM770
• E220
• E1750
  ... and probably more.
