euler_2d_shockbubble_amrclaw: fixed README and added version info
euler_2d_shockbubble_amrclaw: updated Makefile for dimsplit
moved apps/euler_2d_shockbubble to apps/euler/shockbubble/2d_axisym
moved amrclaw/examples/euler_3d_shockbubble to apps/euler/shockbubble/3d -- plan to compare to 2d_axisym version
changed to match 2d_axisym better and to plot rho=0.5 isosurface.  Dimensional splitting is much faster
