Addings/modifications to help files

[sidki3003]

Regarding the alpha: added some missing descriptions:

Config_Control.txt Wrote:Status Bar: Add Page Load Timer (on)
...............................................................................

Measures the time a page takes to load and displays it in the status bar.
In advanced mode a second value is shown: The time after all "onload" and
"DOMContentLoaded" jobs have finished.


Status Bar: Add Time (off)
...............................................................................

Appends the time when the page was last loaded to the status bar text.
Thus partly overlapping with above described "Title: Append Time, Snip Excess"
option.


Status Bar: Add Last-Modified or ETag (off)
...............................................................................

Similar to above described "Title: Append Last-Modified or ETag" option, but
the information is appended to the status bar text instead.

Above attached zip updated.
