* src/find.c: changes to find_parameters/find_file i18n.
* src/widget.c: new function introduced, button_scan_hotkey();
button_new() and button_set_text() fixed to use mentioned function.
* src/key.[ch], src/dlg.c: changes to make recognition of ESC char as
ALT(c) possible for 8-bit chars. (By replacing 'A'/'Z' comparisons with
call to isalpha() in the way proposed by Norbert).
* src/boxes.c: changes to display box i18n
* src/learn.c: changes to learn key dialog i18n
* key.c, key.h (numeric_keypad_mode, application_keypad_mode): New
functions which encapsulate two hardcoded escape sequences from main.c.
* main.c (main): Use the two new functions from key.c
* main.c, screen.c: Moved all file selection keys from the default
keymap to the keymap for panels in listing mode.
Changed *_selection_cmd to *_selection_cmd_panel in panel_keymap
(functions in panel_keymap get a WPanel * as first parameter,
i.e. the indirection with cpanel isn't necessary).
* main.c (midnight_callback): Keys '*' and '-' were not treated
when only_leading_plus_minus==0;
Optimized the if-clauses a little bit (i.e. removed duplicate
checks). More optimation is possible but it would make the whole
stuff completly unreadable.
* key.c (correct_key_code): KP_ADD, KP_SUBTRACT and KP_MULTIPLY
will be translated to +, - and * only if the option
alternate_plus_minus is turned off.
* learn.c (learn_keys): Turn alternate_plus_minus temporarily on
to avoid translation of KP_ADD, KP_SUBTRACT and KP_MULTIPLY in
correct_key_code/make sure keypad is in application mode (makes it
possible to learn this keys).
* cmd.c (reverse_selection_cmd_panel): New function (renamed from
reverse_selection_cmd, takes a WPanel * as parameter, references to
cpanel changed to panel/the passed parameter).
reverse_selection_cmd now simply calls this function with cpanel.
This pair was missing among the *_selection_cmd* functions.
* cmd.h: Added function prototypes.
