Added/enhanced bash with cmder.sh/user-cmder.sh, organized tasks menu

added personal files to .gitignore so they never get uploaded to the repo and added support for msys2 bash in the new git for windows

added autocreate of config/user-cmder.sh if iot does not exist and added it to the .gitignore

Added tasks: cmd::Cmder, cmd::Cmder as Admin, bash::bash, bash::bash as Admin, bash::mintty, bash::mintty as admin, powershell::powershell, powershell::powershell as Admin. Set default task to cmd::Cmder.  Cot rid of init.bat running before /bin/bash, fixes double exit requirement

Added running git for windows post-install.bat on first cmder launch

fixed file/path not found  errors when launching powershell as admin

fixed file/path not found errors when launching bash/mintty as admin

fixed PATH in vendor/cmder.sh

Added sourcing ~/.bashrc if it exists.

changed .gitignore to ignore anything with path of config/user-*

removed my personal files from .gitignore, left in config/user-*

Make sure $CMDER_ROOT does not have a trailing '/'

%CMDER_ROOT% does not have trailing '\'. allow user to specify a conemu.xml on the command line

Removed '\' from %CMDER_ROOT%

vendor/cmder.sh
