add support for system xonshrc file to environ.py

Browse source 
Redefines the XONSHRC environment tuple to include the .xonshrc file in
user's home directory as well as a system-wide file that lives in
/etc/xonshrc (for Linux and OSX) and (TODO) somewhere else on Windows.

Then xonshrc_context does more or less what it always has, except now it
checks and places the contents of both files into the xonsh environment.
