Custom chat methods

[bastimeyer]

This enables chat windows without address and bookmarks bars and also adds support for custom chat applications.

Previously, the chat was being opened by calling require( "nw.gui" ).Shell.openExternal( url ), so it was impossible #60 (comment) to hide the address and bookmarks bar of the browser window. To be able to do this, the browser executable had to be known, so special launch parameters could be set, but by using openExternal there was no way of doing it.

As I've already said here #9 (comment), I wanted to keep it as simple as possible. The most reasonable solution for me was adding a list of supported web browsers with predefined parameters, so those don't have to be inserted by the average user. Support for a custom command line has also been added, so different applications can be used, too.

I'm opening this pull request instead of just merging these changes, because I'd like to have some feedback first.

Right now, there's an issue with the Firefox implementation. The used parameters (firefox -chrome http://www.twitch.tv/CHANNEL/chat) should be correct, but the twitch chat refuses to load and I don't know why this is happening. I'm not a Firefox user, so if someone knows what's going on, please let me know, thanks.

The dropdown is hidden behind the advanced settings, but I'm not sure if this is really needed.

I just tested this with Chrome, IE and Firefox. Chrome and IE works as intended. However I noticed that it will only work correctly when I specify a specific browser. If I keep it on the default setting it will just open a normal window/tab (but I think this might be intended).

With Firefox however I get the same issue you described. I had this problem when javascript is disabled. Is it possible that javascript is disabled when you open a chrome url?

Yes, there is no detection of the system's default browser, so it has to be set by the user.

You are right, this seems to be the case here. hmmm 😕

I'm going to remove Firefox from the list for now, so I can merge this.

The only other method I've found and tried out was firefox -jsconsole "javascript:window.open('http://www.twitch.tv/CHANNEL/chat','_blank','menubar=0,location=0,toolbar=0,personalbar=0,status=0');window.close()", but without any success (popup block, noscript, etc).

I'm not entirely sure, but I think this is impossible without creating another user profile and using a custom theme or installing addons that hide the address and menu bar.
If the user decides to do so, it can be done by choosing the Custom application chat method and this command line firefox -p profilename {url}.
