[PATCH 4111] load .tex child document in relative path crashes lyx.

[Bo Peng]

Symptom:

inset a child document in type include, select a .tex file with
relative path, load. Lyx crashes.

Problem:

In formats.edit(... Filename(file), "text"), file needs to be a full path name.

Patch:

The attached simple patch fixes this. It may also have fixed bug 4107.
 Note that this filename is relative to buffer path.

Problem:

I think "Load" should be renamed to "Edit". .lyx file is edited in
lyx, and others are edited by 'formats.edit(....)'.

Cheers,
Bo
