[Fixed - need to be merged] change FUISegmentedControl font on IOS below 7

[phamquochoan]

The problem: could not change FUISegmentedControl's font, background ... on various state (ios 6.1)
Fix:

Replace:
if ([[[UIDevice currentDevice] systemVersion] compare:@"6.0" options:NSNumericSearch] != NSOrderedAscending)
in setupFont method inside FUISegmentedControl.m
with
[[[UIDevice currentDevice] systemVersion] floatValue] >= 7

Reason: the first one doesn't include ios 6.1

I'm new to github, doesn't know how to use pull/pork/merge ....
