improvement: IBController can check if user installed expected offline/standalone TWS version #138
Description
Expected offline TWS version should have the version number as a part of the path to the installation folder. IBController might check that before trying to run TWS.
Since configured IBController already have the knowledge of TWS_MAJOR_VRSN and TWS_PATH we can add the check into IBControllerStart.sh starter script which does following 2 checks:
- user didn't forget to specify version number (in below example it simple check "not empty string", but might be more precise and check "represent int number >0 and has 3 digits"
- path to TWS installation folder include that version number and exist on the filesystem.

# PLEASE DON'T CHANGE ANYTHING BELOW THIS LINE !!
#==============================================================================
# check if TWS version wis specified (must be present in TWS offline version)
if [ "${TWS_MAJOR_VRSN}" == "" ]; then
echo "error: please set TWS_MAJOR_VRSN variable in $0 script" >&2
exit 1
fi
# check if TWS directory exit and it has 3-digit version number in it
TWS_OFFLINE_DIR="${TWS_PATH}/${TWS_MAJOR_VRSN}"
if [ ! -d "${TWS_OFFLINE_DIR}" ]; then
echo
echo "error: directory '${TWS_OFFLINE_DIR}' does not exist." >&2
echo "IBController can only work with 'offline' (also known as 'standalone')" >&2
echo "version of TWS (or IBGateway). One of distinct features of 'offline' version" >&2
echo "is the presence of TWS version number in the installation directory path." >&2
echo "Example of 'offline' TWS version default path:" >&2
echo " /home/your_user_name/Jts/963" >&2
echo
exit 1
fi
# Notes:

Most probably the gramma should be changed.
