Fixed: CPTabView will now update its tabs labels when the layoutSubviews method is called. Fixes 1926
Fixed: Remove explicit use of Mac OS X 10.5 SDK, replace with "latest OS X"

The fontinfo and imagesize Xcode projects still explicitly refer to using the Mac OS X 10.5 SDK, while all other Xcode projects simply refer to the latest Mac OS X SDK, with no explicit OS version. This change modifies these two projects to mirror other Xcode projects in the project.

Fixes #1957
New : Added protocols CPTableViewDelegate and CPTableViewDataSource

This PR adds protocols CPTableViewDelegate and CPTableViewDataSource

Unit test in Tests/AppKit/CPTableViewTest.j

Fixed: CPNumber>>numberWithBool: breaks CPComparisonPredicate

Commit df2be92 breaks CPComparisonPredicate if one side of the comparison is a property which returns a BOOL.

CPPredicateParser parses literal BOOLs (YES/NO) into 0/1 using CPNumber>>numberWithBool:. CPComparisonPredicate however does not cast a BOOL from a property using numberWithBool:. E.g.

[[YES,NO] filteredArrayUsingPredicate:[CPPredicate predicateWithFormat:'self = YES']]
used to return [true], now it returns [].

This fix addresses the issue by "typecasting" the lhs/rhs values to numbers using CPNumber>>numberWithBool: if they are of type boolean.

Fixes #2028
