tone volume level should be reduced

Bug Description

Currently, the tone-generator uses the overall system volume to dictate what volume the key press tones are played at. At the default setting it is really loud and forces the user to turn down the overall system volume to limit this, which is not desireable.

The tone-generator should be fixed to do one of the following:
1) always play at a fixed volume, like some reasonable percentage of the max volume, i.e. 20%
2) respond to overall volume changes of the system volume at a reduced percentage. For example tone-generator volume range would be 0-30% of the adjusted volume controlled by the slider. This is how iOS works so you can still adjust the tones but they never get louder than a certain point.

NOTE: tone-generator playback should be disabled when silent-mode is on or a tone-dialer specific setting is disabled, but this is a separate issue.

It should do that already, but I'll test in detail tomorrow.

The maximum level is defined in the tone-generator upstart session file (variable DTMF_VOLUME), as a percentage (0..100) of the system volume, (seems to be quite non-linear, e.g. 20 is way louder than 10).

The volume slider is obeyed - but after reboot sometimes forgotten, see bug 598308.

I'll give more detail after testing, but also cc:ing Ricardo, he is working on bug 598308 as well as the overall system default volumes.

Tested in mako HW, image 188:

 * The system volume (set via the slider in System Settings / Sound, or via the volume hard keys) is taken into account when playing DTMF tones.

 * The 'DTMF_VOLUME' variable in /usr/share/upstart/sessions/tone-generator.conf is taken into account as well.

 * This is the case for the dial tones (before a call), and the local playback of DTMF tones during a call, both when routed to earpiece or to loudspeaker.

The default value 'DTMF_VOLUME=20' is pretty loud. If the other system-wide volumes stay unchanged, I'd suggest a change to '10' or thereabouts.

I changed it to 8, as it's then similar to the value used by android (when master volume is at 100%).
