Bugfix: Apex code snippets auto-truncated

[jongpie]

Fixed #756 by truncating the Apex code snippets that are saved in the LogEntry__c fields OriginSourceSnippet__c and ExceptionSourceSnippet__c

• Previously, the code snippet was only limited by the number of lines of code - but for Apex classes & triggers that have very looooooooooooong code on some lines, the code snippet could cause the JSON value to exceed the corresponding field's max length
• Now, the code snippet only grabs the first 1,500 characters - both fields are set to a max of 2,000 characters, allowing 500 characters for the remaining JSON data
