CSSTidy Code

Added fix for quotes in font-face format sub_value (see http://code.google.com/p/web-optimizator/issues/detail?id=280 for more details)

Fixed parsing of font-family with several words (adding quotes if required)

Added line-height:normal (why??? no trace in specification) if no line-height on font shorthand specified.

Fixed PHP notice on undefined index

Fixed minor bug in resolving font-property (numeric / negative / with dot).
A bit improved background-position (now also handles dots in numbers).

Separated shorthands optimization - font now enabled with value 2, font + background - with value 3. Value 1 is completely safe.

Added font property resolving (works by default on optimize_shorthands=1).
Tuned unit tests with settings.
Added unit test about multiple font-family.

Fixed bug with resolving second negative background-position value.

Added ctype_alpha (not very good, because of only English locale) 'clone'

Added unit tests for shorthands (padding / margin / font-weight / background) and properties (CSS1 / CSS2.0 / CSS2.1).
Need to add shorthand for
'font'
Value: [ [ <'font-style'> || <'font-variant'> || <'font-weight'> ]? <'font-size'> [ / <'line-height'> ]? <'font-family'> ] | caption | icon | menu | message-box | small-caption | status-bar | inherit
