flipNext() and flip(to_page) don't work when disableFlipByClick is true

[chaszzzbrown]

When disableByFlipClick is true, flipNext() has no effect; and flipToPage(pagenum) does nothing when the pagenum > currentpage.

Why? Because at line 245 of Flip.ts, the flipNext method simulates a lick at the right edge (top or bottom) of the displayRect and calls .flip(). But at line 80 of Flip.ts, only when disableFlipByClick is true, there is a test to see if the point passed in is within the display bounds; which fails because the x value is NOT strictly less than the displayWidth (it's equal to it).

I don't have the rig set up to recompile and test TypeScript so I won't post a pull request, but the fix is to edit line 245 of Flip.ts so that the x value passed in is a few pxiels less than the displayWidth; e.g. edit line 245 of Flip.ts to read:

x: this.render.getRect().left + this.render.getRect().pageWidth * 2 - 10,

and that fixes both flipNext() and flipToPage. (In my case, I just monkey-patched it.) Hope that helps!
