/*! \class edelib::FileBrowser

This class can be used as a drop-in replacement for fltk::FileBrowser because
it has much of the same API. In addition, it has the following features:
 - uses edelib::MimeType and edelib::Icon to display file icons
 - multicolumn view with columns: file name, type, size, date of last 
modification and file permissions
 - sorting by each column, by clicking on column headers or programmatically
 - renaming files by clicking on a already selected file
 - drag&drop support
 - several other properties for fine tuning of display.

By convention, real filename with full path of each item is stored in its
user_data() so you can easily access it from item callback or using the
const char* system_path(int index) method.

Events that take place on double clicking, dropping files, popup menu etc.
should be implemented in callback, which enables you to create read-write
or read-only widgets as desired (e.g. in file chooser).
