Enable sample exact controls for BassBoost plugin

Browse Source 
Enabled the use of sample exactness on gain control.

After checking the m_bbfx_leftFX.getGain() function, It was found
that this functiomn only sets a member variable, and causes no other
over head, so decided that checking if the value had changed would take more
clock cycles, than the check to see if the value had changhed.
