[jQuery] [autocomplete] a few improvements to autocomplete

[alexbodn . groups]

hello friends,

i have done a few improvements to the autocomplete module, to fix problems and 
improve functionality:

added selectOnly option to autoselect a result if there's only one. this may 
save you a click.

moved the loading indicator to the left side, in case the field is rtl. 
requires a small plugin i made, attached here. a css entry is being added to 
this effect. the included css file has this, but as oposed to the main 
autocomplete.css, colors are given as names. it's nice, but i'm open to changes 
;) .

added substrings, and substringsSeparators. as oposed to multiple, which deals 
with a list of elements separated by a fixed string, substringSeparators is a 
string made of chars, that each and any of them provide a separator between 
autocompletable strings. it supports editing a program with a closed list of 
keywords, and operators and spaces as separators.

added extraFields, a list of names or ids (if prefixed with #) of other fields 
to provide as fieldname=value params to the ajax query. in case names are 
provided, they are expected to be inputs in the same form as the input itself. 
more complex relationship may be found by adding suitable callbacks to 
extraParams, which i'd only ask to receive the $input and the key name as 
parameters.

pasted joern's solution to the ticket http://ui.jquery.com/bugs/ticket/3587, to 
allow pressing of other key combinations while an autocompletable fields has 
focus, and still keep autocompletion valid.

though i can't yet be very specific, i found multiple autocompletion buggy, and 
hope to devote some time to contribute to it's fix too.
