Visualization features and issues

[guerler]

This is to keep track of remaining issues after the upgraded client stack:

• [ ] Pie charts label misplaced
• [x] Horizontal bars, console error
• [ ] Slider in ngl viewer does not work
• [ ] D3 handling in Venn diagram
• [ ] Error in console in Venn
• [x] Scratchbook opens entire panel view
• [ ] Revisit sorting of visualizations
• [x] Export shared features as npm-module
• [x] Job submission tools, Toolshed unable to install R in local test
• [x] Charts conda module
• [ ] Zooming features unavailable for heatmaps and nvd3 plots, d3 version conflicts
• [ ] NVD3 version does not disable transitions
• [ ] Add log-scale and axis min/max options for tabular visualizations
• [ ] Demo video demonstrating limitations which we have to fix in order to make histograms useful. Most important moments (time markers 1:31, 2:32, and 3:50): https://drive.google.com/file/d/0B7a9KfygumZFMTQ3cmppTmhsY3M/view?usp=sharing
• [ ] Augment meta-data access within charts to allow for PDB-chain identification and other dataset related properties. Currently only tabular columns are resolved
• [ ] Would it be possible to add the name of the file in the history as the default chart name (instead of New Chart ?)

Some non-chart visualization required webhelpers: https://github.com/galaxyproject/galaxy/commit/fbd33a57e0033a1547c3bf6f9812dd574cdb36d2. This is just to keep track of it.
