Enabling travis

This will use a build server to validate the sigs against the public
keys

fix ident

Setting before_script and installing gnupg

gpg is already installed :)

import all asc files

More verbose to check build logs
moving orphan sig to another folder
more verbose travis output

Better understanding of what's happening

removing alwaystrust and yes options
Better importing the keys one by one

The build will fail if someone forgot to add the keys in .travis.yml
which is a good thing

Fix file modes, removing and adding executable permissions

*.dmg, *.gz, *.sig files don't really have any business being marked
executable. *.sh files are intended to be executed, and adding
executable modes to the Windows binaries is helpful when cloning the
repository under Cygwin (where if the *.exe does NOT have an
executable mode set, Windows is unable to launch it).
