[LyX/master] h_use_minted is a bool, not a string

[Jean-Marc Lasgouttes]

commit 64667735f41d0ecd0542985f56942bbaa8dce062
Author: Jean-Marc Lasgouttes <lasgout...@lyx.org>

    h_use_minted is a bool, not a string
    
    We have a mix in this file of boolean stored as such or as strings.
    This translates to values written as true/false or 1/0 in .lyx files.
    
    In this case, the value of use_minted could only be true, since the
    char * pointer is non null.
    
    Also add some else clauses.
