Use preset categories in mark name field

[simgislab]

Currently there is a text field and mark button.

We need to add an option that will allow to, instead of typing in mark names, select them from list.

Possible use case:

1. User goes to options and choose option 'Use categories file'
2. After this option is turned on, the user is asked to choose a file with categories names.
3. Categories names is the file with the following structure: id,cat 38,ABCDE 42,FGHIK
4. After cat file is plugged in, user gets the ability to quickly get preset categories in the text area, by typing in a substr.
5. If mark is named after preset, it gets both ID and CAT (as a NAME).
