o.c.swt.rtplot: Import
o.c.trends.databrowser: Import comprehensive update

Most drawing performed in background threads, no longer delaying the UI
thread.
'Autoscale' performed in parallel background threads, using all CPUs to
determine range of traces.
Cursor values determined in background thread via binary search (Not in
UI thread, not via linear search. Also fixes #536).
All configuration options now in 'Properties' view, no plot config that
allows corrupting time axis settings.
All configurable plot options now saved/restored (#428, #632).
Consistently persisting configuration of 'Model', instead of separating
and then diverging the 'Model' and 'XYGraph' settings (#694, #755).
Provide DataBrowserSchema.xsd for current *.plt file format.
Using Java 8 'Instant' for all time operations.
"Edit Items" dialog (for multiple items) has icon, consistent layout.
Plot can show VStatistics std. deviation as well as min/max (#764).
Each added trace starts with a new color, reducing likelyhood of plots
where users cannot determine which trace corresponds to what item
(#213).
Annotation content with placeholders for name, position, value.
Annotation removal dialog right away lists annotations to remove.
Streamlined zoom/pan options with better visual feedback.
After editing 'Color' property of trace or axis, that line in the
properties table is de-selected so user can see the color.
Toolbar more compact.
Dropping of several PVs works (used to drop "[PV1", "PV2,", "LastPV]")
Can "Remove Archive Data Source" even if source has no name (just Key
and URL)
Tables no longer have "vanishing columns" on Linux; enforcing minimum
column width.
databrowser2.feature: Add new plot lib
pom.xml: Use tycho.version 0.21.0 to support java 8
pom.xml: Use tycho.version 0.21.0 to support java 8
swt.rtplot: Replace toolbar 'close' button w/ context menu

Right-alignment of close button was a hack, didn't work on Mac OS X
o.c.trends.databrowser: Configurable label and axis fonts
o.c.trends.databrowser: Ignore initial 'UNDEFINED' sample from PVMgr
o.c.trends.databrowser: Remove unused FontDataUtil
o.c.trends.databrowser: Font cleanup
o.c.trends.databrowser: Handle *.plt without font settings
o.c.trends.databrowser: EditItems fixes

Editing trace 'width' actually used the buffer size value.
Used to 'clone' ModelItems, but Modelitem shouldn't allow clone()
because that cannot really be done efficiently regarding its samples.
o.c.trends.databrowser: ModelItem no longer supports 'clone'

.. since data shouldn't be cloned
o.c.trends.databrowser: One 'waveform_index' per PVItem

Samples have a reference to it and use it. Changing the waveform_index
no longer requires looping over each sample to update its
waveform_index.
o.c.trends.databrowser: Add "Save Changes" option
o.c.trends.databrowser: Fix changelog type
o.c.trends.databrowser: Review locking of PVSamples
o.c.trends.databrowser: Load legacy scale and label fonts
o.c.trends.databrowser: Configurable 'title'

If present, used as the part name instead of file name.
o.c.trends.databrowser: Load legacy <axisSettingsList,plotAreaBackColor>
