Section Index Title Scrolling

[gensc004]

Fixes #125

• Added ability to render native Section Index Title scrolling functionality. This exposes a new boolean prop called sectionIndexTitlesEnabled

• Fixed bug I noticed with the allowsMultipleSelection feature where, when set to false, you could only select one element in a section as intended, but selecting an option under a different section would not deselect the original.

• Fixed a bug in RNTableView/RNAppGlobals.h that would cause the build to fail when running on a mac with a case-sensitive file system.

@gensc004 how to use this feature?

section index is not showing for this

<TableView style={{flex:1}} sectionIndexTitlesEnabled>
	<Section label="A">
		<Item image={require('../assets/trx30.png')} children='A' />
	</Section>
	<Section label="B">
		<Item image={require('../assets/tix30.png')} children='BB' />
		<Item image={require('../assets/psgr30.png')} children='bbb' />
		<Item image={require('../assets/trx30.png')} children='bbbb' />
		<Item image={require('../assets/trx30.png')} children='bbbbb' />
	</Section>
	<Section label="C">
		<Item image={require('../assets/tix30.png')} children='c' />
		<Item image={require('../assets/psgr30.png')} children='cc' />
		<Item image={require('../assets/trx30.png')} children='ccc' />
		<Item image={require('../assets/trx30.png')} children='cccc' />
	</Section>
	<Section label="D">
		<Item image={require('../assets/tix30.png')} children='d' />
		<Item image={require('../assets/psgr30.png')} children='dd' />
		<Item image={require('../assets/trx30.png')} children='ddd' />
		<Item image={require('../assets/trx30.png')} children='dddd' />
	</Section>
</TableView>

@MeKarina, just to clarify your example is sectionIndexTitlesEnabled set to true?

[MeKarina]

@gensc004 yes, just let it blank will set it to true..

do you have an example for this..??

[gensc004]

@MeKarina, After putting together an example I realized that there is a bug with this feature that is ignoring the sectionIndexTitlesEnabled bool and always adding the section titles. That doesn't explain why they aren't showing for you though...

This example is working in my environment, but it doesn't look like that will help you much.

<TableView
      style={{ flex: 1 }}
      sectionIndexTitlesEnabled
>
      <Section label="A">
             <Item key="a" label="a section" />
      </Section>
</TableView>

What version of RN are you on? And could you post a screenshot of what you do see? I wonder if maybe the images rendering in the items could be big enough eclipse the section titles? Sorry if I am not being very helpful.

This PR is slightly broken. Opened #142 to fix it. @MeKarina I don't think that the fix will impact what you are experiencing, so i will keep trying to help.

[MeKarina]

@gensc004 really sorry... i just noticed that latest version of this library hasn't included this PR... so i install this pr and it's working now...

sorry n thank Youu so much.. =)

@MeKarina I am glad it works for you know! If #142 gets merged it will work even better. Wahoo!
