fix line endings

A partial reformatting of the pascal code to have consistent syntax. Things that are still inconsistent. Some switch statements (uVisualGears.pas) are not lined up on the : so the internal code blocks are not aligned (lined up on the start of the label instead). Some function contents are indented against begin/end of function, some are not, some function begin/end are themselves indented (adler32). Also inconsistency in things like assigning of variables (whitespace before :=) and use of brackets in tests. Probably needs further review for possible code errors.
