Fix #174. Validate the slag format of an entry

Because entries.rb limits id_or_slug to [_/0-9a-zA-Z-]+, a page becomes not accessible when its slug includes a space or other invalid characters.
This patch makes sure that a slug matches this regexp.
Tolerate the condition of invalidity.

With ruby 1.8, dm-types automatically convert a slug with invalid characters into valid one.
Therefore the slug should be raise a validation error, or converted to other string.
Replace edit with save. Because "edit" label is strange in edit page.
