Sequential system diagrams now support an Export to Weblab VHDL option, which is tested and working.
Added Start WeblabFPGA button to menu
Several fixes and improvements. Fixed code generation issue which would prevent proper behaviour when using more than one input (multiple input sequential systems now seem to work fine). It is now possible to name combinatorial systems in any way (it's no longer necessary to call them 'base' for them tow ork). Input and output order is now reversed for sequential systems, so that it is more intuitive when testing it in weblab.
