Add "Context" category

[rladstaetter]

Add a 'Category' feature which works like follows:

• you can select a column region (similar to the timestamp window)
• you can define a separator (for example ., ,, ``...)

After that, LogoRRR will have a look at all lines of the log file, sort it, uniq it, partition it using the separator, and create a MenuList with a tree structure which makes it easy and conveniently to activate / deactivate log lines from certain parts of the system.

For example you have following log entries:

2021-05-17 03:39:15.359 app.logorrr.a.x.MgrA INFO          startup without issues  
2021-05-17 03:39:20.356 app.logorrr.a.x.MgrA INFO          startup without issues  
2021-05-17 03:39:25.354 app.logorrr.a.x.MgrA INFO          startup without issues  
2021-05-17 03:39:30.356 app.logorrr.b.x.MgrA INFO          startup without issues  
2021-05-17 03:39:35.356 app.logorrr.b.x.MgrA INFO          startup without issues  
2021-05-17 03:39:40.358 app.logorrr.b.y.MgrB INFO          startup without issues  
2021-05-17 03:39:45.353 app.logorrr.b.y.MgrB INFO          startup without issues  
2021-05-17 03:39:50.356 app.logorrr.b.y.MgrB INFO          startup without issues  
2021-05-17 03:39:55.358 app.logorrr.c.y.MgrB INFO          startup without issues  
2021-05-17 03:40:00.353 app.logorrr.c.y.MgrB INFO          startup without issues  
2021-05-17 03:40:05.356 app.logorrr.c.z.MgrC INFO          startup without issues  
2021-05-17 03:40:10.357 app.logorrr.c.z.MgrC INFO          startup without issues  
2021-05-17 03:40:15.354 app.logorrr.c.z.MgrC INFO          startup without issues  
2021-05-17 03:40:20.354 app.logorrr.a.z.MgrC INFO          startup without issues  
2021-05-17 03:40:25.358 app.logorrr.a.z.MgrC INFO          startup without issues

you could then easily select everything from package app.logorrr.a (and below) etc.

If you use package/classnames in your log you can then observe different components of your system easily.

This sounds like a really awesome feature!
