Add more smart bash aliases

[stocarul]

Right now we only have one alias in the list: https://github.com/algotech/dotaliases/blob/master/doc/bash/cli_aliases.md

We should find few more useful aliases.

General aliases:

• apt-get: sudo apt-get

Control cd command behavior:

• cd..: cd ..
• ..: cd ..
• .2: cd ../../
• .3: cd ../../../
• .4: cd ../../../../
• .5: cd ../../../../../
