Open TagList within a Split Window

[madrobot]

I added an option to allow TagList to open within the current window split.

Just use the following option in your .vimrc

let Tlist_Use_Split_Window = 1

Note:
Tlist_Use_Horiz_Window must be 0

It works beautifully with other plugins like NERDTree, for example:

let Tlist_Use_Horiz_Window = 0
let Tlist_Use_Split_Window = 1
let Tlist_WinHeight = 15
com TTToggle NERDTreeToggle | TlistToggle | wincmd l
