Set to ignore case prompts

• IntelliJ IDEA's code prompts and supplementary functions have a feature: case sensitivity. As shown in the above icon note, the default is First letter only case sensitive.
• The case-sensitive situation is like this: For example, when we enter stringBuffer in a Java code file, IntelliJ IDEA-defaults to not help us prompt or code supplement, but if we enter StringBuffer, we can make code hints and supplements.
• If you want to be case-insensitive, uncheck this option. (Changed to None in the 2017 version of IEDA)
