ohfp 22343234cd Keep addon signature requirement on by default 
We're setting `MOZ_REQUIRE_SIGNING=0` during build, so it's possible to
set `xpinstall.signatures.required` to `false` in `about:config`, should
it be desired to install unsigned addons, while still keeping signatures
required by default with this change.

// Documentation .............. :
// ==============================
//
// "Section" : Description of the settings section separated by "----"
// "Bench Diff" : Impact on the performance of firefox can be a gain or loss of performance
// +100/5000 stand for 2% gained performance and -1500/5000 stand for -30% performance loss
// Performance can be tested here : https://intika.github.io/octane/
// "Pref" : Preference/Settings name and or description followed by links or documentations
// and some time explanation why the setting is commented and ignored.
// "lockPref" : Locked preference can not be changed on firefox, nor by extensions, can only be changed here
// lockPref is used to lock preferences so they cannot be changed through the GUI or about:config.
// In many cases the GUI will change to reflect this, graying out or removing options. Appears
// in about:config as "locked". Some config items require lockPref to be set, such as app.update.enabled.
// It will not work if it set with just pref.
// "pref" : Sets the preference as if a user had set it, every time you start the browser. So users can make changes,
// but they will be erased on restart. If you set a particular preference this way,
// it shows up in about:config as "user set".
// "defaultPref" : Defaulting : Is used to alter the default value, though users can set it normally and their changes will
// be saved between sessions. If preferences are reset to default through the GUI or some other method,
// this is what they will go back to. Appears in about:config as "default".
// "clearPref" : Can be used to "blank" certain preferences. This can be useful e.g. to disable functions
// that rely on comparing version numbers.
