OpenGrok extension for VS Code

• Search for selected text within multiple projects
• Open a file at a line in the default project

This extension contributes the following settings:

• opengrok-vscode.serverURL: the OpenGrok's server URL
• opengrok-vscode.defaultProjectName: the default project to search/open file in
• opengrok-vscode.additionalProjectNames: additional projects used to search
• opengrok-vscode.showInContextMenu: toggles the commands' visibility in the context menu
• opengrok-vscode.openExternal: the command will open the result with the system default application (in browser, e.g.) or in VS Code
• opengrok-vscode.useActiveColumn: applicable only if opengrok-vscode.openExternal is true, will open the results in the active column

Note: if opengrok-vscode.additionalProjectNames is left empty, opengrok-vscode.searchAdditionalProjects won't be visible in the context menu

Added support for showing the results inside VS Code (with the help of https://github.com/xionxiao)
