Improved output control

[ccryx]

Currently, the output of the command is very python-y, i.e. it's just print()-ing python lists containing dictionnaries.
Instead it should print each element of a list on a new line with square brackets and curly braces removed.

Additionally, the behavior when providing --info with one desired piece of information is inconsistent with the other output.
As of now, it only prints the desired piece of information with no additional identifier.
This was done so I could use kphttpc in scripts that query the database for a password.
In place of the current behavior there should be a command line option that toggles script friendly output.
