Enhanced FIND and CHANGE support

RFIND and RCHANGE are remembered across different libraries and across BROWSE, EDIT, and VIEW. For integrity, the first time RCHANGE is performed in a member, Data Set Commander places the command on the command line to allow rejection, modification, or execution of the change command.

Data Set Commander propagates the text search command issued within the MSL into the BROWSE, EDIT, and VIEW. For example, after the following command within MSL:

FINDTEXT 'DATE'

The RFIND command in BROWSE positions the cursor on the first DATE string.
