stale biplex_core fix

fft_biplex in the libraries contained a stale version of the biplex_core
block. This caused errors with setting up the FFT family in some cases.

Internal unscambler in fft_biplex moved to casper_libraries_ffts_internal.
fft_biplex_init changed to fully draw the fft_biplex block with a default
empty state in the library (removing the chance of fft_biplex containing i
a stale block). fft now draws and simulates correctly.
adc_sim, of, conv, of_detect_bus readd

cleanup commit c77818c broke adc083000x2. Added blocks back to ADCs
section.
removing unused files

BEE2 base project
iBOB base project
generic pcores
removing corr bee2 and ibob code from the scripts

also removed framebuffer as it was only used by the iBOB
biplex_cplx_unscrambler fix

biplex_cplx_unscrambler was moved to FFTs/Internal but the link to
the library was not properly disabled. Initialization commands were moved
to a proper script and munge_init added to disable the links.
update library location

It seems there was an idea to create an adc_lib and some blocks were
moved there, but the move was abandoned part way through.
Removing the old gavrt library
updating the conf callback script
adc083000 script clean-ups

removed references to adc_lib.
replaced reuse_line with add_line.
replaced 'simulink/Sources/In1' with 'built-in/Inport'
replaced 'simulink/Sinks/Out1' with 'built-in/Outport'
Added new option to PFB for fanout delay.

All three PFBs (only fully tested with pfb fir real though) have a new option which allows for delays to be added between the address counter and the ROMs that hold the coefficients. For designs with large channel/tap counts, this was becoming a timing bottleneck.

Compare block locations in lower case

The input block location should be converted to lower case as well as the
location found for the block with the same name. (thanks Glen)
