Manual way to enable the XP platform toolset in CMake,
NODEFAULTLIB:LIMCMTD (debug version was missing)
Build setup changes:
- separate folders for cspice32 and cspice64
- option for static linking
- cspice readmes.
Merge branch 'GSOC-Integrator'

Conflicts:
	Particle_Integrator/Code/CMakeLists.txt
v0.14
- Changelog
- CMake Version variable
- Minor corrections in default config value and CMake script.
Resolve gcc warnings:
- remove unused variables
- make sure that solAccel[] is not used uninitialized
- make sure fcloseall is declared
Merge branch 'master' into GSOC-Integrator
Fix possible NULL-pointer fwrite,
.gitignore CMake32 / CMake64 dirs
SAVE_NTH_MULTIPLIER properly implemented for RK76:
imitates behaviour of RK4 for now.
Merge branch 'GSOC-Integrator'
Bugfixes:
- Initialize n_opt with n, is not used but called before being set by calc_save_factor
- Do not optimize (-Og) in DEBUG, seems to break compilation in some cases.
Print release type in all cases,
Additionally for debug builds:
- Date and Time of creation
- Active preprocessor options
Merge branch 'GSOC-Integrator'
Properly initialize structs
(initialization of char arrays was incorrect),
move info printing to function.
Fix for ENDONTIME in RK4:
Missing recalculation of dt2
Merge branch 'GSOC-Integrator'
- fixed bug, that breaks recognising already processed particles for particle numbers > 100k (app tried to continue every particle on restart; may increase time to finish WU if restarted often)
- changed output file name to "binary_output.ctwu"
- added beta to binary output header
Linux platform adjustments
- static libgcc
- no RELWITHDEBINFO for gcc
- debug with -ggdb3
Move interpolation to separate function
- prepare for different algorithms
- prepare for possible config switch of interpolation type
Replace spkezp_c with spkezr_c in RK76:
- returns position and speed vectors of body
- requires slightly different parameter formatting
