Changeset [4c562048dc3df56a3778e82b1b9e1d5712162189] by Aparajita Fishman

More fixes to CPSearchField (Cocoa compliance and bugs):

• Added the ability to specify a separator in the template by using the tag CPSearchFieldSeparatorMenuItemTag.
• recentSearches was not being initialized by -initWithCoder, moved that code into -init.
• -setSearchMenuTemplate was not being invoked. Since having a recents menu is the default behavior in Cocoa, it should probably be the default behavior in cappuccino. To turn it off, set _maximumRecents to >= 254.
• -searchTextRectForBounds was using the wrong rect for -searchButtonRectForBounds and -cancelButtonRectForBounds, resulting in a rect that was too narrow and did not fill the space.
• Tightened up the spacing between the magnifying glass and the text to exactly Cocoa distance.
• Overhauled - updateSearchMenu to fix some logic bugs.
  
• Made sure the search field becomes first responder after closing the search menu.
• Cleared the search string when clearing recent searches, this is what Safari does.
• Removed redundant invoking of -setDelegate in -initWithCoder.
• -init has to be called last in initWithCoder. http://github.com/280north/cappuccino/commit/4c562048dc3df56a3778e8...
