Fixed static analyzer warning

framesetter could be nil (this warning may only occur in Xcode 4)
Add ARCHS_STANDARD_INCLUDING_64_BIT
Added three functions abstracting the fact that CGFloat is bigger in 64Bit land. the appropriate functions for round, floor and ceil are ifdef'd around __LP64__ checks.
Implement the three new CGFloat methods within TTTAttributedLabel
use MAX rather than fmax to avoid warnings on 64bit
encodeWithCoder: encode NSNumbers rather than float values for better 64bit support.
AttributedTableViewCell CGFloat rounding set behind _LP64__ ifdefs

[Issue #274] Resetting links on -setAttributedText:
Bumping version to 1.7.3
Update README.md
Protect self.links for multiple additions of links.

When calling -addLinkToURL:withRange: multiple times, only the last add
is maintained. The underlaying cause is that self.links array is reset
when self.attributedText is set in the method's if (attributes) body.
The alternative fix was to protect the self.links property in the
setAttributedText.
