Fix cmderdev/cmder#3020; hg prompt is slow.

Cmder's hg prompt didn't use async prompt filtering yet.
Cmder's svn prompt only used async prompt filtering if a special config
variable was set (the commit which contributed it seems to have
misunderstood the git config settings for the git async prompt).

This commit makes the following changes:
1.  Adds async prompt filtering for hg.
2.  Makes async prompt filtering for svn the default.
3.  Removes the prompt_overrideSvnStatusOptIn variable.
4.  Fixes a bug where any errors during `svn status` in the svn prompt
    accidentally show up in the terminal.
5.  Fixes a bug where any errors during `hg branch` in the hg prompt
    turn into Lua errors.
6.  Simplifies the code for colors in the hg and svn prompts.
7.  Clean up the svn prompt code and make it consistent with the git
    and hg prompt code.
