#16 Better bookmark management

[george r]

1) automatically check for upper case/lower case characters in the bookomark path. For example: if I enter "C:\documents and settings", I would like it to convert to "C:\Documents and settings"
2) give a name to a bookmark. For example: I'd like to see a lebel like "Work projects" in the bookmarks menu, instead of the actual path
3) allow me to access bookmarks from a column which is displayed next to the tabs (at the BorderLayout.EAST or WEST of the window :) ). I mean: a panel containing a Box(BoxLayout.Y_AXIS), containing several buttons, each fo which displays a label (see point #2)
