[WIP PATCH] Use SIGUSR1 to reload the page

Hi Rodrigo, 

I find your recent idea[0] to refresh the page on local file changes
interesting, and it could be a quite useful feature.

[0] https://github.com/dillo-browser/dillo/issues/255

I imagine it can be triggered with a tool like entr[1]:

ls /tmp/test.html | entr 'pkill -SIGUSR1 dillo'

[1] http://eradman.com/entrproject/

So far, I have a working signal handler which will act upon receipt of
a SIGUSR1 signal. It just prints the signal # to the console right now.
I am trying to make it perform an 'a_UIcmd_reload', but haven't been
successful yet:

dillo.cc:389:19: error: use of undeclared identifier 'vbw'
  a_UIcmd_reload(*vbw);
                  ^
1 error generated

bw.h and uicmd.hh are defined in dillo.cc, so its probably a skill
issue on my end :)

Any hints would be appreciated!

Regards,
Alex
