'Clear file' should preserve the BOM if any

[wiz0u]

When viewing a file that has an explicit BOM, clearing the file should not truncate it to 0 bytes but should preserve the BOM.

Additionally, please add a '...' at the end of the "Clear file" menu caption to clearly show that there will be a confirmation dialog before proceeding.

BOM should be put by whatever is writing to log file. It is not intuitive that in some cases "clear" does leave behind some stuff

[wiz0u]

The writer program logic might be "if file is absent, create and write BOM, and then append the logs" and "if file is present, just append the logs"
So an actual zero-bytes file might confuse the system.

Looks like we need a checkbox in Advanced settings tab for configuring this.
