Package updates.

  - Dropbear 2013.57 -> 2013.58
  - Linux 3.2.43 -> 3.2.44
Fixed Dropbear's OpenSSH incompatibility and added scp.

The Dropbear client was not able to connect to OpenSSH because of the custom
format banner defined by the build script. This commit changes the banner from
"SSH-2.0" to "SSH-2.0-None", which matches the "SSH-2.0-%s" format.

In addition, Dropbear's scp implementation and additional man pages were added.
Package updates.

  - Yad 0.19.1 -> 0.20.3
  - AdvanceCOMP 1.15 -> 1.17
Bug fix - files are decompressed in-place.

So far, decompress_file() decompressed files in place. However, roar-ng II
always calls install_package(), so the packages it produces are uncompressed.

In addition, two minor corrections were added to the GNU Screen and Dia build
scripts.
Added useful aliases to the stock /etc/profile.local.
