icons for ascending and descending nodes ☊ ☋

[archer1572]

In general the symbols used for various positions in orbit are too small, often overlapping, and generally hard to distinguish, especially when intercepts are involved.  One simple things that I think would help make it more visually appealing and distinguishable as well as add a touch or realism would be to use the "correct" symbols for ascending and descending node.  There are even unicode symbols for them - U+206A  ☊  and U+206B   ☊  (copied and pasted from Wikipedia page on astronomical symbols).

Also, one thing I think was under represented in KSP 1 was celestial longitude and indication of reference direction, typically denoted by symbol for Aries:  Symbol  ♈︎  (HTML ♈♈  for the symbol without background).   \♈
