fixed: there was a TTMATH_REREFENCE_ASSERT error in Big::PowUInt() caused by: start.Mul(start)

fixed:   Big::Add incorrectly rounded 'this' when both exponents were equal
         it caused that sometimes when adding a zero the result has changed
         this had impact among other things on FromString() method
         "0,8" had different binary representation from "0,80"
changed: renamed: Big::PowUInt(UInt<pow_size> pow) -> Big::Pow(UInt<pow_size> pow)
         it returns 2 when there is: 0^0
changed: renamed: Big::PowInt(Int<pow_size> pow) -> Big::Pow(Int<pow_size> pow)
         it returns 2 when there is: 0^0 or 0^(-something)
changed: renamed: Big::PowBUInt() -> PowUInt(), Big::PowBInt() -> Big::PowInt()
         they return 2 when the arguments are incorrect (like above)
changed: UInt::SetBitInWord(uint & value, uint bit) is taking the first argument by a reference now,
         the specific bit is set in the 'value' and the method returns the last state of the bit (zero or one)
added:   UInt::GetBit(uint bit_index) - returning the state of the specific bit
changed: UInt::SetBit(uint bit_index) - it's using TTMATH_ASSERT now
changed: Big::Mod2() - it's using mantissa.GetBit() now
added:   Big::operator=(double) and Big::Big(double)
added:   TTMATH_ASSERT somewhere in ttmathuint64.h
added:   UInt::Pow(UInt<value_size> pow) and Int::Pow(Int<value_size> pow)
