lv2lint check errors for release v0.9

[SpotlightKid]

When I check the LV2 bundle of version 0.9 with lv2lint, I get the following errors:

$ lv2lint -Mpack -I bin/Fluida.lv2 https://github.com/brummer10/Fluida.lv2

    [FAIL]  UI Symbols
              binary exports superfluous globally visible symbols: 
                * widget_get_scaled_png
                * _draw_combobox_button
                * _xdg_mime_cache_get_mime_type_for_file
                * have_key_in_matrix
                * os_grab_pointer
                * set_pattern
                * _button_released
                * os_is_directory
                * _xdg_mime_magic_get_buffer_extents
                * add_check_button
                * ... there is more, but the rest is being truncated

For the superfluous exported symbols, falkTX has this solution:

The other error (not sure why it occurs twice) needs to be fixed in Fluida/Fluida.ttl, line 146.

Yep, I've forgotten to re-add some compiler flags to the UI after doing the port to windows. should be fixed now with latest commit.

Confirmed fixed.
