ApplyFilteringOnFileList when clicking R

[higaski]

Very minor request for the search reset button labeled "R". I think the behavior when clicking the button should be identical to the one when clearing all characters from the SearchBuffer. This would be a single line fix by adding a call to ApplyFilteringOnFileList after clearing the searchTag:

ImGuiFileDialog/ImGuiFileDialog/ImGuiFileDialog.cpp

Line 897 in 72205b3

searchTag.clear();

Also, thank you for this great addition to ImGui.
