TTS split the text and renders it per sentence.
Now streams whole chapter (very hacky)
Now changes pages in time with the reading.
Disabled seeking.
Fixed comments.
First start or reading pointer.

Also fixed TTS so it always starts with the first word of the page,
and doesn't wast time splitting text before the current position.
Reveresed long-click and short-click actions for the library.
Merge branch '2.0_bugfix'
Fixed the page-offset calculation.

This is a fix for #299 where too much white space was used at the bottom
of the page. The error was caused by subtracting both the margin and the
space used by the page number.
Added algorithm version.

Since we changed the algorithm, all pagenumbers calculated with the old
algorithm need to be recalculated. By adding this field we can determine
this.

Fixed bug where reversal of click / long click didn't work.
Merge branch '2.0_bugfix'
Now actually saves the algorith number :)
Merge branch '2.0_bugfix'
Implemented reading pointer for TTS.

While TTS is active, a small circle under the text will indicate the
current reading position.
