Info_notepad support

[Unusuario2]

I back ported this entity from HLA (only the icon). It is pretty useful for making comments for entity related stuff.

Here is a quick description: https://developer.valvesoftware.com/wiki/Info_notepad

Note, when merging this branch also merge this PR: mapbase-source/mapbase-game-src#5

It is pretty useful indeed. Made my own called hammer_notes well before S2. I'd suggest pairing this with either a VBSP tweak, have it detect and strip these, or a game tweak to just tie them to info_null. Or even directly skip. Amusingly Valve did neither in Alyx so you can see it warning about the unrecognised entity.

I will do a vbsp tweak (copy paste info_null code and change info_null to info notepad) it is pretty straight forward.

technically I think any entity can have the message field added with smartedit off

anyway consider adding something like this I added for logic_script in my fgds

rendercolor(color255) : "Sprite Icon Color" : "255 255 255" : "Helper color to differentiate your script icons. Only works in Hammer++."

this would let you change the icon color yourself in case you had multiple notes. ideally you would want the icon to be white by default and have this RGB color be yellow perhaps
