add dark mode support, warnings for big dirs
1. All forms will now be colored to match the Notepad++ theme. This is true in dark mode and also with non-dark-mode themes that the user might use (e.g., Vim Dark Blue, Blackboard). However, the background of the DataGridView containing the filename rows is bugged in a very weird way. Hopefully someone can figure that out. 2. Added a system for checking if the current directory is very large and could potentially cause tremendously long latency when the user has chosen recursive subdirectory search. Now a warning will pop up if there are more than 5000 files in the current directory tree, so that the user can choose to search only the top directory, or not to search that dir at all.
