I've done some work on the codes page including improving the Javascript so that it
* No longer uses "alert" to show the messages but puts up a kind of message box.
* Allows one to enter all of the JIS code symbols
* Trims the string to remove whitespace
The design is also improved somewhat.
This is in response to a user who wanted to be able to input the 々 symbol via the codes page.
The Javascript/CSS version changed to 102 with this since some files and CSS changed.
