Add manual seed input for rando generation (#2057)

Browse source 
* add manual seed input for rando generation

* add tooltip for seed input

* switch to calloc

* add seed testing count generator

* add console command for rando gen

* add boost and custom hash_32 functions

* use hash_32 funcs for rando generation

* limit seed input field to uint32

* rename custom boost header imports to boost_custom
