Allow using multiple constructor arguments for configuring elements

Browse Source 
Disable undocumented ability to specify aliases as arguments
for constructors, e.g. parser:option("-f", "--foo"), and instead
order properties and pass constructor arguments to them.
E.g. parser:argument("foo", "A foo that bars") sets argument
name to foo and description to "A foo that bars".

TODO: remove "aliases" property, instead allow setting several
names in one string by separating them using space.
TODO: reorder properties so that most useful ones could be used
as constructor arguments.
