Refactor EZBlocker for Improved Readability, Performance, and Maintai…

[drmayor2004]

This commit includes several improvements to the EZBlocker project:

1. Encapsulation and Code Organization:

   • Private fields are now prefixed with an underscore (_) to differentiate them from local variables.
   • Related methods are grouped together for improved readability.
   • Moved DllImport statements to a separate static class to keep the main class cleaner.

2. Error Handling Enhancements:

   • Replaced generic exception handling with more specific exceptions (e.g., WebException, FileNotFoundException).
   • Centralized exception logging to make it easier to manage and track errors across the application.

3. Performance Improvements:

   • Reduced unnecessary UI updates by checking if the content of UI elements (like StatusLabel) has actually changed before updating.
   • Adjusted MainTimer intervals only when necessary, avoiding redundant operations.
   • Used async/await for long-running operations like checking for updates, improving UI responsiveness.

4. Code Refactoring:

   • Replaced magic numbers with named constants, improving code readability.
   • Moved all string literals to constants or used resources where appropriate to facilitate easier localization and modification.
   • Refactored repetitive code into reusable methods, adhering to the DRY (Don't Repeat Yourself) principle.

5. UI Thread Safety:

   • Ensured that UI updates are performed on the UI thread using Invoke or BeginInvoke where necessary.

6. Initial Setup Improvements:

   • Enhanced the initial setup process by encapsulating the setup logic into dedicated methods.
   • Improved handling of Spotify startup and ensured that Spotify is started only if necessary.

7. Other Improvements:

   • Added detailed comments for better code documentation.
   • Improved exception handling in various parts of the code to ensure the application fails gracefully.
   • Enhanced overall code readability and maintainability.
