Add --ie32 commandline option to webdriver_manager

[rogierschouten]

Fixes #1297

The new option allows to download the 32-bit version of the IE driver on
a 64-bit system, as the 64-bit version has been broken for over a year
now (the sendKeys() function works very slowly on it).

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

CLAs look good, thanks!

This doesn't do anything. The line for (bin in binaries) {... actually adds all the instructions for the binary installations.

[hankduan]

Maybe change the name of the binary to 'IEDriver-32bit', and remove the describe statement.

@rogierschouten Have you tested it? I can't test it right now since I don't have a windows machine, but the code looks good. As soon as you can confirm that you tested it, and sign the CLA again, I'll pull it in.

[rogierschouten]

I plan to test it at work next Monday, I can't do so now either. I'll let you know, thank you
