Fixes memory leak in move-value filter when Settings is selected as the Move Value Type.

[FiniteSingularity]

The obs_data_t *setting in the Move Value filter's load_properties function was not being released in all cases. Added in an increment to the reference counter if setting is assigned to item2, and then releases setting at the end of the function call.

In addition, item was not being released in the while loop in move_value_load_properties.

Finally, this PR adds version.h and resource.rc to the .gitignore file for devs who are using the git command line.

Fixes #216
