I checked with @fxn last night before making this change.
use default_options= instead of default to avoid confusion
Globalize2 is only compatible with Rails 2 so link to Globalize3 instead
Add quotes to Numeric Passwords to force string(Postgres)

If you have numeric password for your database, like below:
```yaml
development:
  adapter: mysql2
  encoding: utf8
  database: myblog_development
  pool: 5
  username: root
  password: 123456
```
you will get the following obscure error with unhelpful stack-trace

so adding a note informing about numeric passwords seems like a good idea
Add quotes to Numeric Passwords to force string(sqlserver)

If you have numeric password for your database, like below:
```yaml
development:
  adapter: mysql2
  encoding: utf8
  database: myblog_development
  pool: 5
  username: root
  password: 123456
```


you will get the following obscure error with unhelpful stack-trace

repeating documentation for form helpers
`config.action_mailer.async` is no longer used
Add multipart: true to form for file upload.

I was slightly overzealous when removing this before.

Identified here: https://github.com/rails/rails/commit/ed78770b1a13788a5d3fcae484f34654de580bd5\#commitcomment-2281181
Prevent raising EOFError on multipart GET request.

Such request can happen on Internet Explorer. When we redirect
after multipart form submission, the request type is changed
to GET, but Content-Type is preserved as multipart. GET request
cannot have multipart body and that caused Rails to fail.

It's similar fix to Rack's one:
https://github.com/chneukirchen/rack/blob/8025a4ae9477d1e6231344c2b7d795aa9b3717b6/lib/rack/request.rb#L224
Merge pull request #8476 from sheerun/fix/multipart-get

Prevent raising EOFError on multipart GET request.
