[FIX] calendar: support non-ascii chars in date/time format

The calendar module generates string values with
a date/time formatted according to the user
language. Those formats may contain non-ascii
characters and are read as unicode strings,
but fed to str{p,t}time, which only accepts
byte strings (in Python 2).

This would cause an exception when loading calendar
notifications for a user using e.g. Chinese with
some CJK unicode chars in the date/time format.
[FIX] fix autocompletion problems with quick presses

Problem was that when the user types quickly in the search bar and press
enter, the keydown event of the enter key happens before the keypress
event of the last key entered.  This means that the autocompletion has
a wrong string.  The fix is to move the enter selection detection from
keydown to keyup.

[FIX] web_calendar: improve the commit 787147d. This commit was fixing bug in other module that calendar which was open an event in popup view. Because browse/read by default was unable to read string id. The fix was too restrictif, because calendar need to read/browse string; we cannot cast this id in Int else we loose the virtual part. parseInt('12-20140512') -> 12.

[FIX] tools: find_in_path: config is not ready at import time

commit f76d4525a was not actually working: extra keys from
config files are not yet into the config options dict at
import time. The fix is to move the logic inside the method,
like in `find_pg_tool` just below.

Also fix the use of `find_in_path` in report.py: the subprocess
may also raise AttributeError exception, so instead of listing
all the possible ones just re-raise the IOError shallowed by
`find_in_path` when the result is None.

Fixes #3809 #3811
