1. If Tlist_Ctags_Cmd variable is not set, on startup, check for the
presence of exuberant-ctags or ctags or tags in the PATH and set
Tlist_Ctags_Cmd variable accordingly. If none of the executable is
found, then the taglist plugin will not be not loaded.
2. Added a new configuration variable Tlist_Enable_Fold_Column to
enable or disable fold columns in the taglist window.
3. Added support for setting the taglist application name used by the
winmanager plugin and the cream package.
4. Two new key mappings ([[ and ]]) are added to the taglist window to
move between files.
5. When a file is modified, the taglist window will be automatically
updated (after going to some other window or buffer and then coming
to the modified buffer).
6. Made the Tlist_Update_File_Tags() function as a global function.
This function can be used to add or update the tags for a new file.
7. Updated the Tlist_Get_Tag_Prototype_By_Line() and the
Tlist_Get_Tagname_By_Line() functions to get the tag name and tag
prototype for the specified line in a file.
Added support for closing the tags tree for inactive files, removing the tags tree for deleted buffers, processing the tags when the taglist window is not opened, disabling the automatic highlighting of the current tag, displaying name of the current tag.
