Update Xfce Terminal Font line

[skipster1337]

General description of bug:

• What happened: Xfce developers rewrote the configuration manager for the terminal, terminalrc is now obsolete and no longer used by xfce4-terminal.
• What should happen: The terminal font line should get pulled from ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-terminal.xml instead.
• Did it work in an older version: It should work with a version of xfce4-terminal older than 1.1.0
• Where did you get the binary: Arch Linux repositories
• Does this issue still occurs in the latest dev build? yes
