Added a new public method to reload only the appearance of the tabs
UIView’s that is used as tabs are now have auto resizing by width and height

This way, changes in tabs' sizes are reflected to their contents as well. This provides contents to be centered in every size.

Fix UI jerkiness when calling selectTabAtIndex

You can see the underlying bug in the sample app prior to this patch. 

Run the sample app and turn on slow animations (cmd + t in the simulator). Tap the 'Tab #5' button and notice that the tab bar immediately changes to tab 5, then animates left, then jumps back to center on tab 5.  

In the debugger you can see that this is because it's hitting [self.tabsView scrollRectToVisible:frame animated:NO] in scrollViewDidScroll:

An example implementation of reloading content after a period of time. We can say this is a simulation of remote content fetching.
Set the color of temporary view controller’s view’s background to clearColor, so that there won’t be a UI jerkiness when user tries to scroll the content while it’s loading.
Added DS_Store to gitignore.
Lowered required iOS SDK version to 6.0

It was set to 6.1 but I don't think there's anything that requires
strictly SDK 6.1.
Fixed a tab scrolling bug.

Before this, sometimes tab won't follow by scrolling when content view
is paged by swipe gestures. This was caused when `animatingToTab`
property is set to `YES` and never gets back to `NO` again. So I just
worked around this by adding a completion handler to cases that was not
handling this property. I'm not sure that was intentional or not, but
for me this fix works well.
Lowered target iOS version of xcodeproj as well.
Fixed #35.

The first plan for this fix was just to workaround not to pass
`NSNotFound` to `selectTabAtIndex:`, but I found `selectTabAtIndex:`
doesn't take out-of-bounds arguments into account. In private methods
like `viewControllerAtIndex:` handles invalid arguments collectly so I
decided follow this way. Notice that `selectTabAtIndex:` is a public
method which behaviour will be changed by this fix.
