- Fetch charsets from collations dataset rather than firing an extra "SHOW CHARSET"
- Move fetching defaultCharset to existing TRY clause. No functionality change, just more consistent.
- Sort all comboboxes with charsets and collations alphabetically
- Leave the responsibility for disabling the comboboxes on old servers to the code rather than to the DFM file.
- Adapt Enabled-property of TLables to the comboboxes they belong to.
* Make export table locks local to current connection work.
* Bugfix: In non-file mode, export commands go directly to server without being parsed; thus they must not have semicolons at end of sentence. A regression here causes issue #1747558 and issue #1795486, which this commit fixes again.
(Briefly considered adding a cleanSql() which just runs result := parseSql(sql)[0], which would do the same in fewer lines of code, albeit with the small overhead of having the semicolon both added and afterwards removed again..)
