Exception when compiling program w/o opt_attribs

[Olliebrown]

The version on the main web page and downloaded as the latest release has a bug where it raises an exception when you try to compile a program without providing the 'opt_attribs'

To reproduce: open the tiny.js example and notice it does not work.

Problem seems to be around twgl.js:1823:

} else if (!Array.isArray(opt_attribs)) { var options = opt_attribs;
opt_errorCallback = options.errorCallback;
opt_attrib = options.attribLocations;
}

Quick fix is to check that opt_attribs is defined before checking if it is an array:

} else if (opt_attribs && !Array.isArray(opt_attribs)) {
var options = opt_attribs;
opt_errorCallback = options.errorCallback;
opt_attribs = options.attribLocations;
}

Also, notice that the last line of the conditional block referenced 'opt_attrib' w/o an 's' which I think is a type-o. I assume it should be 'opt_attribs'

Note, the relevant line in the src is in programs.js:435:

} else if (!Array.isArray(opt_attribs)) {
var options = opt_attribs;
opt_errorCallback = options.errorCallback;
opt_attrib = options.attribLocations;
}

Sorry about that. I think it's fixed now.
