server-vampire's Issues

Small bug in parsing

I'm using Vampire v4.7 (commit 7c473653c), and the model/parsing.py falters with the line_type identification. For instance, the line_type is reported as " replaced by" instead of "replaced by" which then confuses gleiss/saturation-visualization causing it to get stuck with the message "Waiting for Vampire..." showing.

Steps to reproduce error:

1. Start vampire-server locally
2. Open saturation-visualization app
3. Set input language to TPTP and fill the input field with the following:

fof(define_less,axiom,(
    ![X,Y] : (less(X,Y) => (? [Z] : (less(X,Z) & less(Z,Y)))) )).

fof(derive_more,axiom,(
    ![X,Y] : (less(X,Y) <=> more(Y,X)) )).

fof(more_dense,conjecture,(
    ![X,Y] : (more(X,Y) => (? [Z] : (more(X,Z) & more(Z,Y)))) )).

4. Click "Find proof"

Expected behavior: Screen stuck on "Waiting for Vampire..."
