Leaks file handle of model in labeling mode

[crawlserv]

When using a model to label some text, valgrind gave me:

==5332== HEAP SUMMARY:
==5332==     in use at exit: 472 bytes in 1 blocks
==5332==   total heap usage: 602,017 allocs, 602,016 frees, 1,352,158,567 bytes allocated

==5332==         suppressed: 0 bytes in 0 blocks

It seems like this file handle is not closed:

Wapiti/src/wapiti.c

Line 195 in 569fbe5

FILE *file = fopen(mdl->opt->model, "r");

A simple fclose(file); after the following line should suffice:

Wapiti/src/wapiti.c

Line 198 in 569fbe5

mdl_load(mdl, file);

Cheers!
