There was a quasi-bug that caused that
hdlmake was trying to remove some submodules
after thier parent modules were removed. This
generated error messages. Now the modules are
removed in reverse order compared to fetching

Until now it was sometimes necessary to run
hdlmake multiple times in order to fetch specified
modules. This bug is now fixed and a single
run is needed.

There was a bug fixed because of which hdl-make
didn't work properly without specifying run
parameters (there was no default action)

There was a bug that caused wrong dependency
solving for Verilog files. As reasult, there were
misleading error messages printed (like
Cannot find include for file src/lm32_shifter.v: l)

A bug was fixed, when there was and error when trying to
generate a makefile for synthesis with ISE, when there was
no Modelsim installation. Hdlmake was trying to look
for modelsim.ini in order to check which libraries were
``standard''.
