[texworks] Typesetting paths

[Jérome Laurens]

Hi,

In the upper part of the Preferences -> Typesetting pane,
you can set up the path to the binary tools for typesetting.

On mac os x, the standard path for tex related binary tools is /usr/texbin
which is a soft link that points to the actual tex distribution.
Based on this soft link, there is a very user friendly mechanism that helps people
managing their tex distributions.

In texworks, if we add this path using the + button,
the soft link is resolved and only the destination is recorded,
such that /usr/texbin cannot be added to the list.
This breaks the default management of tex distributions on os x
and forces everyone to update texworks by hand when the distribution updates.
