Enhance the .gitignore file to suit more environments

[DavidAntliff]

For https://github.com/pongasoft/re-blank-plugin/releases/tag/v1.0.0

The current .gitignore can be enhanced to support more cases and build environments (such as Visual Studio and CLion). For example:

*.pyc
.cache/
__pycache__/
*/.idea/workspace.xml
*/.idea/tasks.xml
*/.idea/vcs.xml
*/.idea/

# CLion
cmake-*/
build/
*.plist
temp.txt

# VC++ 2010
UpgradeLog.XML
*.vcxproj.user
*.suo
*.sdf
*.ucd.txt
*.ncb
*.opensdf
ipch/

# VisualStudio build
/Debug/
/Backup/
/VisualDebugging/
dependencytest.*
