[issue8232] webbrowser.open incomplete on Windows

In order to fix the issue I added on to the WindowsDefault class so that it is the main browser class for windows platforms as opposed to being a default when no other browser is given. I gave the class an init where it specifies specific flags for firefox, chrome, and internet explorer (from what I could find there aren't really new window or new tab flags for internet explorer). If the flags for other browsers are known they should be easy to add to this section.

        def __init__(self,browser = "windows-default"):
            # Grab the different flags for the different browser types
            browser.lower()
            self.browsername = browser
            # If get() is used without arguments browser will be passed None
            if browser == "windows_default" or browser == None:
                self.cmd = "start"
            elif browser == 'iexplore' or browser == 'internet explorer':
                self.cmd = "start iexplore"
                self.newwindow = ""
                self.newtab = ""
            elif browser == "chrome":
                self.cmd = "start chrome.exe"
                self.newwindow = "-new-window"
                self.newtab = "-new-tab"
            elif browser == "firefox":
                self.cmd = "start firefox.exe"
                self.newwindow = "-new-window"
                self.newtab = "-new-tab"
            else:
                raise Error('The browser you entered (%s) is not currently supported on windows' % browser)

In the open method of the WindowsDefault class I changed how the browser is opened by building a command from the flags and the cmd for the specific browser and used subprocess,call.

            # Format the command for optional arguments and add the url
            if new == 1:
                self.cmd += " " + self.newwindow
            elif new == 2:
                self.cmd += " " + self.newtab
            self.cmd += " " + url

            subprocess.call(self.cmd,shell = True)

This allows the user to input different new arguments to open a new window or new tab like the documentation says they should be able to do. I added a little bit to the beginning of the get function so that it passes its argument to the WindowsDefault class and returns that object on Windows systems.

    # Let the windows default class handle different browsers on windows
    if sys.platform[:3] == "win":
        return WindowsDefault(using)

This adds some of the desired compatibility but does not completely address the module's issues. I did not see a way to open a web page in a currently open page on any of the browsers, just new windows and new tabs (when no flags are passed the browsers default to one of these two options). Also the _isexecutable function's attempt at windows compatibility is still not working because I was unsure of how to use just a string of a browser name like 'chrome' to determine if a file is on a system. This leaves _tryorder not properly containing the browsers on the system. This leaves the module's open, open_new and open_new_tab not properly working either just the WindowsDefault open method.
Any feed back and direction from here is most welcome.
