Add User Config for Editor 2

Editor 2 uses one config file, which changed with every update. I need every time add argument -xmx4g in config file for use 4g memory in editor.

My request make special user_config file with same parameters which add to main config. It resolve problem with edit config every time.

For example:

config file have vmargs = -Ddefold.resourcespath=
in user_config add vmargs = -Xmx4g

Editor read both files and use vmargs = -Xmx4g, -Ddefold.resourcespath=
