Increasing usability and design of files diff. (#413)

Applying sizes. Additional changes. First changes. Merge branch 'master' into diff-cleaner Fixing formatting. Merge branch 'master' into diff-cleaner Final changes for working with custom themes. Merge remote-tracking branch 'remotes/main/master' into diff-cleaner First changes for working with custom themes. Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Adding custom COLOR_FONT. Even smaller cleanups. Merge remote-tracking branch 'remotes/main/master' into diff-cleaner Small cleanups. Fixing bug and adding maximum line limit. Adding option to set cursor to end and small cleanup. First aid. Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Merge branch 'master' into diff-cleaner Few improvements. Performance improvements and cleanups. Minor improvements (code in order) and many bug fixes Bug fix. Combining cited code. Adding code commenting option. Renaming list_files_diffs_new to list_files_diffs Moving ProcessBar into center Increasing performance. Applying size to all icons globally. Removing another unused file. Merge remote-tracking branch 'remotes/main/master' into diff-cleaner Removing unused files. Changing size of 'close'-button. Major changes concerning design and bug fixes. Temporary save point. 2 1 Co-authored-by: opyale <example@example.com> Reviewed-on: https://gitea.com/gitnex/GitNex/pulls/413 Reviewed-by: 6543 <6543@noreply.gitea.io> Reviewed-by: M M Arif <mmarif@swatian.com>
