Inconsistent .css('font-weight') return values

[whatthejeff]

The origin of this issue is:  https://github.com/jquery/jquery/commit/b9b87d53c681a8337cdbdbe81f8f4e577e5ec277

In WebKit/Blink browsers, window.getComputedStyle returns the following for font-weight:

• "100"
• "200"
• "300"
• "normal"
• "500"
• "600"
• "bold"
• "800"
• "900"

In WebKit/Blink browsers, .css() returns the following for font-weight:

• "100"
• "200"
• "300"
• 400
• "500"
• "600"
• "bold"
• "800"
• "900"

It's inconsistent that the return type for normal/400 is a Number when the return type for all other values is a String.

It's also a little confusing that "normal" is converted to a numeric value, but "bold" is not.

In other browsers, both window.getComputedStyle and .css() return numeric strings for all values. This seems like the most desirable behavior.

Seems that once again we're halfway in to fixing a messy rare edge case, one that probably matters for 1% of all users since it's survived this long. The spec does say that "bold" ==> 700 though so we could attempt to fix this.

Let's fix "400" but not "bold".
