IE XHR method polyfill

[michaelpapworth]

At line 30 of /src/ajax/xhr.js I've added a prefilter which resolves bug #13240, my branch taken from the 1.11.0-beta2 tag since the issue only effects IE<9 therefore not required as part of 2.x

This won't work because we don't support ActiveXObject in the 2.x branch. I'm backing out a commit I made that implied we did.

[dmethvin]

Sorry, ignore that comment.

@michaelpapworth could please rebase this with current 1.x-master.

@michaelpapworth Please sing our CLA.

Also, you shouldn't base your patch on a release tag but on a pure 1.x-master branch as @markelog said. See http://contribute.jquery.org/commits-and-pull-requests/

[michaelpapworth]

@mzgol I've signed the CLA and re-based my branch against 1.x-master.

Thanks

@michaelpapworth There's still a lot of noise here. Look at the commits tab - there should be only one commit and it should be yours. Since you based your patch on the release tag, there are all this unnecessary dist/ & bower_modules/ files here.

EDIT: you should revert all this three Dave commits and then squash everything using git rebase -i 1.x-master. See e.g. http://ariejan.net/2011/07/05/git-squash-your-latests-commits-into-one/ for how to do that.

[michaelpapworth]

I've had some issues trying to squash these, I've decided for the sake of a few lines of code I'll start over and submit a new pull request (#1460)

@michaelpapworth You didn't have to close it, you could re-create your patch on a separate branch and then reset your branch to it (with --hard). Then git push --force would reset your pull request to the new version, keeping all comments history etc.

[michaelpapworth]

@mzgol I'm sorry but I'm relatively new to GitHub and unfamiliar with the command line Kung Fu that goes with it. Should I continue with the new pull and abandon this one?

[mgol]

@michaelpapworth Yes, since you've already created one, let's continue there.
