Bug 1249556 - Implement toggling details by keyboard. r=smaug

Browse Source 
The user can switch to the main <summary> by tab key, and toggle the
<details> by either 'space' key or 'enter' key.

'return' key is handled with 'keypress', and the 'space' key is handled
with 'keyup' like the HTMLInputElement.
