Added support for time lapse video capture.

Changes in individual files:

VideoCamera.java:
- Added swith to time lapse option in Menu.
- initializeHeadUpDisplay(): sets up display according to the
  current mode (timelapse/no timelapse).
- readTimeLapseVideoPreferences(): sets parameters according to
  the chosen quality. Eventually this should move to CamcorderProfile
  through media_profiles.xml files.
- switchTimeLapseMode(): handles switching between time lapse mode
  normal mode.
- Since preview size may be different from video size for HD time lapse
  capture, we save the desired preview size in mDesiredPreviewWidth,
  mDesiredPreviewHeight and use it for comparison in
  resetCameraParameters().
- Time lapse mode is enabled/disabled by calling
  mMediaRecorder.setTimeLapseParameters().

CamcorderHeadUpDisplay.java: Constructor now takes in a boolean
(captureTimeLapse) telling whether to enable time lapse quality
options or the normal camcorder quality options.

Camera.java: Moved getOptimalPreviewSize() to Util.java to enable
use from VideoCamera.java. Also needed to pass activity, so that can
use getWindowManager(), getSystemService().

CameraSettings.java: added support for time lapse parameters. The
function getVideoTimeLapseQuality() returns the quality identifier
from the passed in string.

res/: added string, array values for time lapse.

res/xml/video_time_lapse_preferences.xml: contains all the preferences
for time lapse mode.
