skel: add bash aliases/settings:

- we use .bash_aliases since it's sourced from ~/.bashrc and it prevents overwriting the /etc/skel/.bashrc file provided by the bash package
 - add some useful aliases/shorthands for frequently used commands
 - add ls aliases
 - force color prompts
 - load autojump
 - Prevent ">" from overwriting existing files
 - set some bash history settings
 - set git promp configuration
 - enable colors in manpages
 - add other examples
