Text re-flow enhancements

[Google Code Exporter]

Although I am very grateful for the text re-flow addition, it is seriously 
lacking in functionality. If you could fix these issues, APV would remain the 
best reader out there (IMHO). I'm currently using RepliGo for books that need 
re-flow, so I know these fixes are possible.

1. Color options. I use the red text, but with re-flow enabled the text becomes 
white.

2. Zoom. While re-flow does make the text slightly larger, it isn't large 
enough. Being able to make the text larger/smaller would be great.

3. Prev/Next Page. The buttons at the bottom are completely unnecessary. I'm 
sure everyone who uses this app either use Vol buttons, or page swipe.

Thanks for an amazing app/reader, and keep up the good work!
