Patch fixes

[jgray-19]

An updated version of #367 with the comments taken into account

Fixes List

• Make all patches follow trkfun format.
• Add third argument to patches so that they run in trackone
• Fix tilt so that srotation is performed in C and Lua
• Fix symmetry between Lua and C
• Make Lua and C attitude to optional arguments and m.d(the/phi/psi) identical
• Force tilt in Lua and C to work the same
• Fix changeref weighting

[ldeniau]

• patches as element must use elm.angle -> m.ang & cflw.ang
• misalign must use m.mang (we should simplify/remove the use ang in etrck)
• no other maps use m.ang of cflw.ang
• thus srotation used as tilt can use m.ang and cflw.ang. This simplifies a lot the code.

accepted for now, but it is not the correct way to do the rotation for the tilt

• patches as element must use elm.angle -> m.ang & cflw.ang

  • thus srotation used as tilt can use m.ang and cflw.ang. This simplifies a lot the code.

In this case, would you like me to change the sbend_thick (in c++), which currently uses m.ang. Then change the patches (in c++) (x/y/s)rotation to use m.ang instead of the current m.d(the/phi/psi)
