contrib: split pypats list in check-code.py This is a part of preparation to apply checking with check-code.py on code fragments embedded in *.t test scripts. Ideally, all patterns in "pypats" before this patch should be applied on not only normal *.py files but also code fragments embedded in *.t test scripts. But fixing test scripts for some patterns requires many changes, and has less profit than effort. Therefore, this patch splits pypats list into two below: - commonpypats, which are applied on all (= including code fragments embedded in *.t test scripts) *.py files - pypats, which are applied only on normal *.py

{
    // Enforcing
    "eqeqeq"        : true,     // true: Require triple equals (===) for comparison
    "forin"         : true,     // true: Require filtering for..in loops with obj.hasOwnProperty()
    "freeze"        : true,     // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
    "nonbsp"        : true,     // true: Prohibit "non-breaking whitespace" characters.
    "undef"         : true,     // true: Require all non-global variables to be declared (prevents global leaks)

    // Environments
    "browser"       : true      // Web Browser (window, document, etc)
