Update some of our functions to cover some fixes for vulnerability issues.

Updated README.md and DESCRIPTION.rst to reflect the new functionality.

Small bug fix release.

• Fixed the paci list command to work as expected.

This is a rather big release.

Reworked the whole paci list command

This is a new behavior! It will now display the available packages by default not the installed ones. This is how you can use it:

• paci list - this will print all available packages from the registries. (new default)
• paci list (-i | --installed) - this will print all currently installed packages. (old default)

Also a description text was added to avoid confusion.

Reworked and fixed displaying of tables

Tables/lists now look a little cleaner and take up less space. Also they are now automatically adapting to the available space on the screen. You now should have nice looking list on every screen.

Added missing documentation

A description of all available options was added to the ones which were lacking one.

Minor stuff

Also the some text was added to the output of paci search to make it more clear.

Adds the option --debug to the paci install command. If you are using Python and the paci libs for packages then it will display the output of the commands right away.

Adds the output of the command as a return value to the run_cmd function.
It extends the library to use in INSTALL.sh or UPDATE.sh scripts.

Adds an option to the print_heading to specify the color in which it should be printed.

Refactored to use DESCRIPTION.rst instead. This should now fix the formatting on pypi.

Use README.rst instead of REAMDE.md for displaying the pypi entry.
This should fix the crappy formatting.
