[Nightly] Update v0.7.3844a

[h3]Changelog[/h3]

Repository system implemented:

- Added apt-get program in the filesystem on all computers.

- Added repository-server installer in shops to host repositories. After installing, check the configuration file /server/conf/repod.conf

- Added librepository.so library

- By default you have access to the official repository with the operating system libraries, such as init.so, net.so, etc. To disable this access, edit the file /etc/apt/sources.txt

- Now the hackshops have a repository server enabled, pointing to the web tools with the metaxploit.so and crypto.so libraries as well as the rest of the programs.

- Added methods in scripting shell.apt_show, shell.apt_search, shell.apt_update, shell.apt_add_repo, shell.apt_install and shell.apt_check_upgrade

- Fixed bug in metalib.lib_name when returning the name of the file instead of the name of the library

- Replaced "under construction" web pages by simple web pages.

- Fixed Bug 583 - Domain names can be generated with a / inside the name
