Correctly set the module name, and let it actually test the Lightdm lens.
Small fixes to improve documentation:

- Declare a module name in test_yum, so that gets taken instead of Yum.lns
- Filter is a view, not a variable in ntpd.aug
- Properly declare the module name nginx.aug
Fix some more broken module names
Move the 'coding' comment to the end of the file to fix the menu entry.
regen Menu.txt after recent changes.
Basic documentation for final apt lenses and sync Menu.txt
Properly document this lens.
Sync View comment with actual definition.

AptPreferences: Simplify/Standardize the module
AptPreferences: adjust a little bit to simplified lens
Modify the Nagios lens to handle resources.cfg too.

Fixes ticket #312

Add two files found on OpenBSD to the simplevars lens.
Quote: Allow multiple spaces in quote_spaces
* acinclude.m4: only turn on FORTIFY_SOURCE if it won't anger gcc

Following libvirt commits cf9bced0 and 1c2edf0f
* .gitignore: ignore test result files (*.trs)
Shellvars: ignore network configs with ! in their name

NetworkManager would write such files, but that leads to problems during
aug_init, as the attempt to create the node
/augeas/files/etc/sysconfig/network-scripts/FILE!NAME will fail as that is
not a valid path expression
augparse: add --trace option

Using --trace will print the filenames of all modules that are loaded.
