Support input as multiple files

[liyawang]

The way we are browsing datastore is confusing, e.g., user needs to use double click to open a folder, single click to select a folder or file.

One idea to improve might be adding Glyphicon checkbox before folder and file, also add Glyphicon folder and file to distinguish them.

• Single click will open the folder
• Folder can be selected with the checkbox
• File can be selected with the checkbox
• Multiple files can be selected with multiple checkboxes (might need to use ; to separate them in the URL field and need extra code to format them for Agave)

Further functions are needed since we need to browse more locations inside/outside of datastore and more operations to support. From left to right we should have

• Home (glyphicon Home, /iplant/home/some_user/sci_data, gray out 'Home' if not log in, not allowed to go up this level)
• Community Data (glyphicon Community Data, /iplant/home/shared/, gray out 'Community_data' if not log in, not allowed to go up this level)
• Public (glyphicon Public, data.sciapps.org/example_data/, not allowed to go up this level)
• glyphicon Go Up (grayed out for all three options on the left on certain levels)
• glyicon Refresh (won't refresh the entire page. Since we cached the list in browser, this will be helpful for new additions)
• glyicon Get All Files (shall we allow select all folders? Danger)
