Put Input Signal Names in 'Tabs'

[Raffzahn]

Puting input signal names into 'vonnection tas' coudl improve readability. Especially as long input signals are not front alligened.

Output signals may be handled similar.

As long as there is no way to mark inner connections in systems with several output signaly (from different gates), this could help to distinguish 'real' inpust from internal.

Internal is defined as an input signal name used in any other clause used as outout. External is defined as a signal name nowhere else used as Input, or an out put signal namenowhere else used as input.
