--Bug fixes

Browse Source 
-Fix improper usage of rand() in cpow2, cpow3, hypertile1, hypertile3D1, hypertile3D2, juliac, juliaq.
 -Fix program crashing during density filtering on some Nvidia cards.
 -hypertile3D1 was wrong.
 -Parsing phoenix_julia when coming from Apophysis was wrong.
 -Density filtering was freezing on certain Nvidia cards.

--Code changes
 -Optimize juliac, npolar.
 -Add a new function Crand() which behaves like the legacy C rand() which returns an integer between 0 and 32766, inclusive.
 -Use RandBit() in some places.
 -Remove Zeps() from vignette, it's not needed.
 -Restructure OpenCL code for density filtering such that it does not hang after being compiled on some Nvidia cards, such as the gtx 1660. Remove barriers from conditionals where possible.
