Notifications preflet and notification_server

Notifications preflet:
-Use sliders instead of text fields for width and timeout
-Remove icon size choice (mini icon looks horrible)
-Consolidate both "Enable" checkboxes into one
-Fix Revert button, remove Apply button, add Defaults button
-All changes to settings saved immediately
-Live example notification message shown when settings changes are made
-Add setting for individual apps to specify whether their notifications
should be muted
-Remove history list (to be implemented later)

BNotification class:
-BNotification records the signature and name of application that
created it
-New functions to get source application signature and name

Notification Server:
-Notification pop up view layout fixes and bold font size fix
-Remove notifications history from AppUsage class (will be saved in
cache instead)
-Remove vector of NotificationView objects which isn't needed
-Get source application info from notification object, not the received
message which is not reliable

Patch by plfiorini: Integration of InfoPopper as a system service. See ticket
#1245. There are some TODOs outlined in the ticket, but they will be much
easier to review as individual patches against trunk, versus as a new version
of the huge patch.

I've messed a lot with src/servers/notification/NotificationsView.cpp in order
to resolve a crash I was getting when testing this thing (rewrote line
wrapping). I've also replaced the icons with the one that zuMi did long ago.

Thanks, plfiorini, for working on this code as much as you did!
