Automatically update symbols after "up".

[KaiMartin]

If a symbol was changed after "down-symbol" these changese very likely are intended to propagate to the current schematic. Currently, this involves manual interaction by the user:
a) save symbol
b) do "up-symbol"
c) select the affected symbols
d) do "update symbols"

Step c) is particular error prone if the project contains more than one instance of the symbol. I'd appreciate, if save and update symbols could be done automatically.
