Aaron Vaage 440adb3086 Remove Text Time Scale Assumption From Cue Alignment
In the cue aligner, we assumed that all text will be in milliseconds.
This was the last place with that assumption. This change removes that
assumption and uses the stream info's time scale.

Issue #399

Aaron Vaage 2e9c2fe024 Fix Cue Insertion at Text Stream End
Problem : Text samples have variable length and therefore act
          more like continuous samples whereas audio and video
          act more like discrete samples. Since we use sample
          start time, a cue event could be inserted after the
          start time of the last text sample and never get
          inserted as there are no more samples.

Change : After all streams have requested flushing, we make sure
         to collect all remaining cue events from the sync point
         queue and insert them into each stream.

Aaron Vaage f619affb8f Store More Than One Cue
In the cue alignment handler, instead of storing just one cue, store
a full queue. This will make it easier to handle text streams that
end before audio and text.

Aaron Vaage ff0fd500b8 Store Stream Data and Not CueEvent
In the cue aligner, instead of storing the cue event, store a
stream data so that we don't need to know the stream index when
sending the cue event downstream.

Aaron Vaage ec3bbfff16 Isolate Video and Non Video Actions In Cue Aligner
To make it easier to understand what a video stream and a non
video streams is doing in the cue aligner, each stream type is
given their own functions.

Aaron Vaage df19a48aa0 Use Common Hint
Use a common hint for all stream states as the hint is always
updated when we get a new cue event. Cue events are only gotten
when be pass the hint, so there should only need to be one hint.

Aaron Vaage 3b5b2bccca Implements SyncPointQueue and CueAlignmentHandler
SyncPointQueue manages all cue points and returns aligned cue
points to the callers (CueAlignmentHandlers).

CueAlignmentHandler is responsible for aligning cues from different
streams. It uses SyncPointQueue internally to align / synchronize the
cue points.
