Update Makerbot

[stuartpb]

Stray observations:

registration form

• also has "country" and "industry" dropdowns
• includes "Sign up for MakerBot communications" checked box (#175)

reset password request form

• has two "Or, go back to login" links, one for Makerbot's login form and one for Thingiverse, probably due to sloppiness in the template (the one on Thingiverse only has the Thingiverse link)
• requesting a second password reset token invalidates the previous one

reset password email

• yes, requesting from makerbot.com sends the email from thingiverse.com, too - and they both link to a page on makerbot.com

reset password change form

• username is displayed on the page
• destination is the main page of Thingiverse (https://www.thingiverse.com/), where you are logged in
• does not reject all-spaces password

change password form

• going to accounts.makerbot.com when logged in from Thingiverse (after password reset) logs you into makerbot.com, slowly (or maybe you're already logged in and there's just a slow spinner on page load for no reason?)
• all the labels on the form say they're for username, probably some sloppy copy+pasting in the template
• there's a similar page on Thingiverse that has the username in the URL
• I set the password to a 9000-character one, which was accepted, then I tried changing the password with an additional character appended to the "old password" and it was accepted, so they're probably not using the whole thing (bcrypt?)
