GDL 0.8.11 released

GDL now became much faster. The actual increase in speed depends upon several factors but up to 60% seems to not be unrealistic. Some new important subroutines were implemented, including CREATE_STRUCT, CONTOUR, LAGUERRE, and STRCMP. SYSTIME now has sub-millisecond resolution. For the FFT procedure, the FFTW library can (alternatively) be used, resulting in about double the execution speed.
