Extensively rename classes, etc., in OKS-related code

...as mentioned at this morning's OKS meeting. The name changes are detailed here:

A first round of merges was performed on Friday. Saturday on Slack Alessandro pointed out that the following changes were still needed:

• DataReceiverModule needs to be changed to DataReaderModule
• DPDKReader to DPDKReaderModule (I believe he's already done this)
• FDFakeCardReader to FDFakeCardReaderModule

[jcfreeman2]

Further renames for today:

• WIBConfigurator -> WIBModule
• DataReceiverModule -> DataReaderModule, DataReceiverConf -> DataReaderConf

For the latter case, changes that made it onto the develop branch of appmodel overnight meant that DataReceiverModule persisted despite this morning's merge of johnfreeman/daq-release_issue376_renames_for_v5_pt2

Closing this; three waves of name changes have been successfully performed and further changes are addressed in later issues (e.g., #379)

Complete; changes going in to fddaq-v5.1.0
