* Fix for window positioning
With default case having multiple vertically split windows, the tagbar
window should open on the far right of the screen. When the feature in
pull-request 630 was added, this behavior changed to open the tagbar
window relative to the current window. This commit will fix that by
allowing direct usage of the vim split options.
Validated the following cases for the old default values. These all
still behave the same way as prior to pull-request 630 when the tagbar
is activated in the `active` window shown in the below examples:
```
" No options
+-----------------------------------+
| preview |
+--------+--------+--------+--------+
| edit | edit | edit | tagbar |
| | active | | |
+--------+--------+--------+--------+
" tagbar on left, preview above
let g:tagbar_left = 1
+-----------------------------------+
| preview |
+--------+--------+--------+--------+
| tagbar | edit | edit | edit |
| | | active | |
+--------+--------+--------+--------+
" tagbar on bottom, preview to right of tagbar
let g:tagbar_vertical = 10
+--------+---------------+--------+
| edit | edit | edit |
| | active | |
| +-----+---------+ |
| | tag | preview | |
+--------+-----+---------+--------+
" tagbar on top, preview to the right of tagbar
let g:tagbar_left = 1
let g:tagbar_vertical = 10
+--------+-----+---------+--------+
| edit | tag | preview | edit |
| +-----+---------+ |
| | edit | |
| | active | |
+--------+---------------+--------+
```
New values also all validated using the following:
```
" Behaves the same as no options
let g:tagbar_position = 'right'
" Behaves the same as g:tagbar_left = 1
let g:tagbar_position = 'left'
" Behaves the same as g:tagbar_vertical = <#>
let g:tagbar_position = 'bottom'
" Behaves the same as g:tagbar_left = 1 | g:tagbar_vertical = <#>
let g:tagbar_position = 'top'
```
* #650 - Fix typo in doc/tagbar.txt for g:tagbar_height option
New configuration option for g:tagbar_position that will supercede g:tagbar_left. This option allows for new values for 'top', 'bottom', 'left' and 'right' (default:'right') to position the Tagbar window.
New configuration option for g:tagbar_height that will supercede g:tagbar_vertical. This option is used to set the Tagbar window height when the window is split using the 'top' or 'bottom' position.
New configuration option for g:tagbar_no_status_line. This option will disable any Tagbar status line updates in the event another plugin is controlling the status line. This prevents Tagbar from changing the status line when Tagbar is not the active window.
