Filename globbing support

[gber]

I would find filename globbing support very useful, e.g. for including files when the filenames are not known in advance using something like

for = /etc/uwsgi/conf.d/*.ini
include %(_)
endfor

good idea, i will make a patch soon (but using the current "for" will lead to all sort of problems, so i will add a for-glob instruction)

[unbit]

added for-glob

You can test it with:

[uwsgi]
socket = :4141
for-glob = /etc/*
print = %(_)
endfor =

if it is working well you should see items printed in startup logs

Works fine, thanks a lot!

I think I need a combination of for-glob and for-readline to be able to read env-files.
