Hi,

I thought it might be useful to have some new-style power and I/O symbols 
in the standard library, so I tried to distil a "standard" version of each 
of the styles currently in use:

     https://bugs.hedmen.org/tmp/pwr-io-symbols.png

The symbols are functionally equivalent (each symbol has a netname= 
attribute which specifies the net to which it is connected, visible by 
default for all but the ground symbols), they only differ in their visual 
representation and can be used interchangably.

There is a second set of input/output symbols for subschematic ports which 
have a portname= instead of a netname= attribute but are otherwise 
identical.

Any thoughts or comments?

Roland
